Let's roll up our sleeves and get these comparison problems solved!
Understanding the Basics: Powers and Order of Operations
Before we jump straight into the complex calculations for A and B, let's have a quick refresher on the absolute fundamentals of mathematics that we'll be using. Trust me, getting these basics down is half the battle when you're solving intricate expressions. First up, we've got exponents, those little superscript numbers that tell you how many times a base number is multiplied by itself. For example, 5² isn't 5 times 2; it's 5 × 5 = 25. Super important, right? And when you're dealing with powers of the same base, things get even cooler. Remember these golden rules:
- Multiplication of powers: When you multiply numbers with the same base, you add their exponents. So, xᵃ × xᵇ = xᵃ⁺ᵇ. Easy peasy!
- Division of powers: When you divide numbers with the same base, you subtract their exponents. So, xᵃ ÷ xᵇ = xᵃ⁻ᵇ. Another gem!
- Power of a power: If you have a power raised to another power, you multiply the exponents. So, (xᵃ)ᵇ = xᵃᵇ. This one pops up a lot, so keep an eye out!
- Different bases, same exponent: Sometimes you'll see numbers like (ab)ⁿ = aⁿbⁿ or (a/b)ⁿ = aⁿ/bⁿ. These are super handy for simplifying things.
- Zero exponent: Any non-zero number raised to the power of zero is 1. So, x⁰ = 1 (as long as x isn't zero). This is a tiny but mighty rule.
- Negative exponent: x⁻ⁿ = 1/xⁿ. While less common in our specific problem today, it's a good one to keep in your back pocket for future algebraic manipulations.
Now, let's talk about the grand boss of all mathematical operations: the Order of Operations. This is where most people get tripped up if they're not careful. We usually use the acronym PEMDAS or BODMAS to remember the sequence:
- P/B: Parentheses/Brackets first! Always, always, always deal with anything inside parentheses or brackets before anything else. It's like a VIP section for calculations. These enclosures dictate what operations have to be completed before anything outside them can be considered. Ignoring these can completely change the value of an expression.
- E/O: Exponents/Orders next! After clearing the parentheses, tackle all those tricky exponents. This means evaluating
x²,y³, etc., before moving on to multiplication or division. Remember, exponents represent repeated multiplication, and their impact is significant. - MD: Multiplication and Division (from left to right). These two have equal priority. If you see both, just work your way from the left side of the expression to the right. Don't prioritize multiplication over division or vice-versa; it's strictly about which one appears first as you read from left to right.
- AS: Addition and Subtraction (from left to right). Again, equal priority. Once all the multiplication and division are done, sweep through from left to right, handling additions and subtractions. Similar to multiplication and division, there's no inherent priority between addition and subtraction; you simply perform them as they appear from left to right.
It's super critical to follow this order meticulously, guys. One tiny slip, like doing an addition before a multiplication, and your whole answer goes kablooey! These foundational mathematical principles are the bedrock for simplifying complex equations like the ones for A and B. We'll be applying these rules constantly as we work through the problem. Think of these as your superpowers in the world of numerical analysis. Mastering these basic arithmetic and algebraic rules is the first step towards confidently approaching any challenging mathematical comparison. So, take a moment, review these concepts, and ensure they're locked in your brain. This isn't just busy work; it's truly the key to unlocking the solutions to our complex numbers. We want to make sure you're fully equipped to tackle exponents and operators with precision, avoiding common pitfalls that can derail an otherwise correct calculation. Remember, a solid grasp of these fundamental mathematical operations will save you a ton of headaches later on and will be invaluable for accurately evaluating mathematical expressions.
Decoding Number A: A Step-by-Step Breakdown
Alright, let's roll up our sleeves and get started with our first contender, number A! This is where we'll put all those exponent rules and order of operations into action. Remember, precision is key here, so let's take it one chunk at a time. The expression for A looks like this:
a = 13⁴ ÷ 13³ - 5² × 5⁵ ÷ 5⁶ + 17⁹ ÷ (17²)⁴ + [59 - 6² + 3 × (12⁴ ÷ 2⁷ ÷ 3³ - 4)] × 5
Initial Power Calculations for A
First things first, let's simplify all those individual power terms using our exponent rules. These are the low-hanging fruits, guys, and tackling them early makes the whole expression less daunting.
13⁴ ÷ 13³: Here we have division of powers with the same base. What do we do? Subtract the exponents! So, 13^(4-3) = 13¹ = 13. Boom, first part simplified. This is a classic application of the division rule for exponents, streamlining the expression immediately.5² × 5⁵ ÷ 5⁶: This one involves both multiplication and division of powers with the same base. We add exponents for multiplication and subtract for division. So, 5^(2+5-6) = 5^(7-6) = 5¹ = 5. Another piece done. Keeping track of the sequence for adding and subtracting exponents is crucial here.17⁹ ÷ (17²)⁴: Ah, a power of a power here! First, resolve (17²)⁴. Remember, we multiply the exponents: 17^(2×4) = 17⁸. Now, we have17⁹ ÷ 17⁸. Again, division of powers, so we subtract exponents: 17^(9-8) = 17¹ = 17. Looking good! This demonstrates the two-step process: simplify the inner exponent first, then apply the division rule.6²: This is just 6 multiplied by itself: 6 × 6 = 36. Simple, but crucial not to miss! Basic square calculations are often embedded and need to be handled early.
So, after our initial power-play, the expression for A has already shrunk significantly:
a = 13 - 5 + 17 + [59 - 36 + 3 × (12⁴ ÷ 2⁷ ÷ 3³ - 4)] × 5
See? Much friendlier already! Now, let's dive into that big bracket, respecting the order of operations.
Tackling the Brackets in A
This is where the order of operations truly shines. We need to work from the innermost parentheses outwards. Inside our big square bracket, we have [59 - 36 + 3 × (12⁴ ÷ 2⁷ ÷ 3³ - 4)]. And inside that, another set of parentheses: (12⁴ ÷ 2⁷ ÷ 3³ - 4). Let's conquer that inner one first, as PEMDAS dictates!
12⁴ ÷ 2⁷ ÷ 3³: This looks a bit tricky because the bases are different, but we can make them the same! Remember that 12 can be written as 2² × 3. So,12⁴becomes(2² × 3)⁴. Using our power of a product rule, this expands to2⁸ × 3⁴. This is a fantastic example of base transformation to apply exponent rules. Now the expression is(2⁸ × 3⁴) ÷ 2⁷ ÷ 3³. Let's group the same bases:(2⁸ ÷ 2⁷) × (3⁴ ÷ 3³). Using the division of powers rule, we get2^(8-7) × 3^(4-3) = 2¹ × 3¹ = 2 × 3 = **6**. Phew! That was a neat trick, right? This step really showcases the power of exponent manipulation and how recognizing common factors can simplify things dramatically.- Now, back to the inner parenthesis:
(6 - 4). This is straightforward: 2. Simple subtraction, but it relies on the previous complex exponent simplification.
Awesome! The inner parenthesis is resolved. Let's substitute that back into the main square bracket:
[59 - 36 + 3 × 2]
Following PEMDAS, we do the multiplication before addition/subtraction:
3 × 2 = 6
Now, the bracket becomes: [59 - 36 + 6]
Next, we perform the addition and subtraction from left to right:
59 - 36 = 2323 + 6 = 29
And just like that, the entire complex bracket simplifies down to 29! See how breaking it down makes it way less intimidating? This methodical approach, moving from innermost to outermost, is your best friend when simplifying complex mathematical expressions.
Finalizing the Value of A
We've done all the heavy lifting! Let's bring everything back together to find the final value of A.
Remember where we left off:
a = 13 - 5 + 17 + [result of bracket] × 5
Substituting the bracket's value (29):
a = 13 - 5 + 17 + 29 × 5
According to PEMDAS, multiplication comes before addition and subtraction:
29 × 5 = 145
Now, the expression is just a simple string of additions and subtractions:
a = 13 - 5 + 17 + 145
Perform these from left to right:
13 - 5 = 88 + 17 = 2525 + 145 = 170
Voila! We have our first number: A = 170.
This journey through evaluating number A was a fantastic workout for our mathematical skills. We applied multiple exponent rules, strictly adhered to the order of operations, and meticulously simplified nested expressions. This process is a testament to how breaking down a large, complex problem into smaller, manageable chunks makes it entirely solvable. Understanding each sub-step is crucial for preventing errors and ensuring accuracy. We learned how to transform different bases into common ones for division, a handy trick indeed! The satisfaction of seeing a huge expression collapse into a single, neat number is pretty awesome, isn't it? Take a deep breath, congratulate yourself, because you just navigated a significant chunk of complex arithmetic with flying colors!
Cracking Number B: Unveiling Its Value
Alright, guys, time for number B! Don't let its length scare you; we're going to use the exact same systematic approach we mastered with A. Just like before, we'll break it down, apply our exponent rules and order of operations, and conquer it piece by piece. You're already a pro at this, so consider B your next challenge to cement those problem-solving skills. Here's the expression for B:
b = 144 ÷ 12² + 19⁴¹ ÷ (19²)²⁰ - 8¹⁰ ÷ 4¹⁴ + 10 × [83 - 9² + 6 × (43⁵ × 43⁶ ÷ 43¹⁰ - 23)]
Looks busy, right? But remember our strategy: simplify powers first, then tackle brackets, and finally, the remaining operations. This consistent approach is what makes solving complex numerical problems achievable and reduces the chance of errors.
Initial Power Play for B
Let's get those exponents sorted out. These initial simplifications always make the expression look much cleaner and less intimidating. Each of these steps is a mini-victory in our overall quest to evaluate the expression for B.
12²: Simple multiplication: 12 × 12 = 144. This one's easy, but super important for the first term in B. Basic squares are often disguised within larger expressions, so spotting and resolving them early is a good habit.19⁴¹ ÷ (19²)²⁰: Another power of a power situation! Resolve(19²)²⁰first by multiplying the exponents: 19^(2×20) = 19⁴⁰. This is a direct application of the power of a power rule. Now we have19⁴¹ ÷ 19⁴⁰. With division of powers with the same base, we subtract the exponents: 19^(41-40) = 19¹ = 19. Another one down! This two-step simplification is key to handling chained exponent operations.8¹⁰ ÷ 4¹⁴: This is a classic case where the bases are different, but we can make them the same by converting them to powers of 2. Recognizing common prime factors is a crucial skill here. Remember,8 = 2³and4 = 2². So,8¹⁰becomes(2³)¹⁰ = 2³⁰. Applying the power of a power rule once again. And4¹⁴becomes(2²)¹⁴ = 2²⁸. Same rule, different base. Now the expression is2³⁰ ÷ 2²⁸. Using the division rule for exponents, we subtract the exponents: 2^(30-28) = 2² = 4. Fantastic! This is a common trick, and mastering it helps a lot in simplifying complex exponential terms where bases aren't initially identical. It’s a testament to the versatility of exponent rules.9²: Another straightforward one: 9 × 9 = 81. Don't overlook these simple steps, as they are just as crucial as the more complex ones for overall accuracy!43⁵ × 43⁶ ÷ 43¹⁰: Here, we have multiplication and division of powers with the same base. We add exponents for multiplication and subtract for division: 43^(5+6-10) = 43^(11-10) = 43¹ = 43. This demonstrates combining multiple exponent rules in a single sequence.
Phew! After all those power calculations, B is already looking much more manageable:
b = 144 ÷ 144 + 19 - 4 + 10 × [83 - 81 + 6 × (43 - 23)]
See how much cleaner it is now? We’ve taken some seriously complicated bits and reduced them to single, simple numbers. This is the beauty of applying mathematical rules consistently and methodically, setting us up for the next phase of simplification.
Diving into B's Brackets
Just like with A, our next mission is to conquer the nested brackets. The expression inside the big square bracket is [83 - 81 + 6 × (43 - 23)]. We'll start with the innermost parentheses: (43 - 23). This is the top priority according to PEMDAS.
43 - 23 = **20**. Easy peasy! A simple subtraction, but vital for unwrapping the bracket.
Now substitute that back into the square bracket:
[83 - 81 + 6 × 20]
Following PEMDAS, multiplication comes before addition and subtraction:
6 × 20 = 120
The bracket now looks like: [83 - 81 + 120]
Finally, perform the addition and subtraction from left to right:
83 - 81 = 22 + 120 = 122
And there you have it! The entire large bracket simplifies to 122. You're doing great, guys! Breaking down these multi-step operations is truly the secret sauce to success. This methodical approach minimizes errors and ensures that every part of the expression is handled correctly, leading to a much clearer path towards the final solution.
Assembling the Full Value of B
We're almost there! Let's bring all our simplified parts together to find the grand total for B. This final consolidation requires careful attention to the order of operations to avoid any last-minute slip-ups.
Recall the expression after our initial power simplifications:
b = 144 ÷ 144 + 19 - 4 + 10 × [result of bracket]
Substitute the value of the bracket (122):
b = 144 ÷ 144 + 19 - 4 + 10 × 122
Time for PEMDAS again! Division and multiplication come first, from left to right.
144 ÷ 144 = 1(Any non-zero number divided by itself is 1. A fundamental rule of division!)10 × 122 = 1220
Now the expression is simplified to a string of additions and subtractions:
b = 1 + 19 - 4 + 1220
Perform these from left to right:
1 + 19 = 2020 - 4 = 1616 + 1220 = 1236
And there you have it! Our second number is B = 1236.
Seriously, give yourselves a pat on the back! You've just navigated another incredibly dense mathematical expression and emerged victorious. The journey through calculating number B reinforced all our principles: careful handling of exponents with different bases, meticulous application of the order of operations, and the strategic simplification of nested expressions. This kind of detailed work not only leads to the correct answer but also builds your mathematical resilience and analytical thinking. You're becoming a true master of numerical simplification!

This is the exciting culmination of all our hard work in evaluating complex expressions, where precision at every step truly pays off.
Let's recap what we found:
- Number A = 170
- Number B = 1236
Now, the question is: how do these two stack up against each other? Is A greater than B, or is B greater than A, or are they miraculously equal? This is the grand finale, the moment where all our hard work in evaluating complex expressions truly pays off.
When we compare 170 and 1236, it's pretty clear, isn't it? We can visually tell that one number is substantially larger than the other. There's no trickery or subtle difference here. The difference in magnitude is quite stark, making the numerical comparison straightforward.
- 170 is a much smaller number than 1236.
Therefore, we can confidently conclude that:
B > A
Or, if you prefer, A < B. Both statements convey the same truth: Number B is significantly larger than Number A. This final comparison step might seem simple after all that hard work, but it's the culmination of every single calculation we performed. It's the payoff for being meticulous with exponents and diligent with the order of operations.
