It takes about eight seconds to see that that's 2^18.

Definitely not an Olympiad level problem.

Yeah, pretty obvious that the one and everything past the one goes away immediately

Now solve that in your head. I got 262144 from 512^2

I know the powers of two instantly from direct memory up through 2^16, but I usually then have to calculate a bit. I've just never bothered to learn the higher powers. I spent my career working in the digital hardware area, but by the time powers higher than 65536 started to become "more relevant" I had moved on to other facets of the work, so those beyond 16 just never got "burned in" like the lower ones did. I can give them all to you in hexadecimal, though. 🙂 0x40000. There's a reason we made so much use of hex.

for computer person - after you get to 2^18 = 2^10 ( 1K ) * 256 - multiply that - easier than all that stuff after 2^18 in this video. Or 2^18 =- 2^20 (1M ) /4. both give the correct answer and easier.

Before watching: Alright, if you have like a^b^c^d^e^f^g, you'll typically calculate f^g first, then e^(f^g), then d^(e^(f^g)), and so on,. With that in mind, we can ignore the outermost 3 exponents we see. Why? Because those last 3 are 1^(5^9)), and 5^9 is a real number, and 1^X = 1 for real X. So what this actually meansi s that we're looking at √ 2^(6^2). But square root is simply an exponent of 1/2. Thus, √(2^(6^2)) = (2^((1/2)6^2)) = 2^(36/2) = 2^18. Solution is 2^18. Because we're not solving for X, but simply evaluating a square root, we do not include the negative root in this case. Most math classes will allow you to leave the term 2^18 as-is. However, if your class is currently doing a unit on *evaluating* exponents, you may have to multiply it out. Quickest way without knowing the higher powers of 2 (suppose you only know as far as...2^12 = 4096) would be to do (2^9)(2^9) = 512*512 = 1024 + 5120 +256000 = 262144 Honestly 4096*64 is probably going to go faster, but I went with what popped into my head.

I think this problem is more interesting if instead of solving for the square root of 2^6^2^1^5^9 you solve for the square root of 2^6^2^1^4^4 which has an answer with same digits as the problem

Good

@shouryakeshkar5309 27 күн бұрын

oml bruh you can straight up cancel out the 1^5^9 and get sqrt(2^6^2) = 2^18 its that simple dont overcomplicate things take it easy

They're just going step by step for novices who might not see it as quickly. There's other channels for more advanced math stuff.

Why is everyone thinking of 2^18 , I think its 2^36 , since there is whole underroot therefore it will be 9^(1/2).

2^18 The key is you need to recognize that 1

@andredcavalcante 6 күн бұрын

Forget powers of 1: result is always 1. 2 power 1 is 2. 6 power 2 = 36. But you are in a square root, and a square root of any number power 2 is this number. Then, square number of 2 power 36 is 2 power 18. Then, the result is 2 power 18 = 512 x 512 Piece cake!

Forget about the top three numbers. One to the power of anything equals one.
