I saw this meme posted on Facebook and I don’t understand. According to the comments, I am supposed to interpet this as 2\^18 = 262144, but why the square root? Also I thought that when it was a “power tower” of exponents like that, you worked from right to left, in which case it would be a ridiciously big number and certainly not be 262144?

You can mostly evaluate this pretty easily up until the end.

You’re right that you evaluate right to left (top to bottom) as such:

sqrt(2^6^2^1^**4^4** ) = sqrt(2^6^2^**1^256** ) = sqrt(2^6^**2^1** ) = sqrt(2^**6^2** ) = sqrt(**2^36** ), where I’ve bolded the part of the exponent I’m evaluating at each step for clarity.

Then you can either evaluate sqrt(2^36 ) = 262144 as is, or further simplify (recall sqrt(2) = 2^1/2 ) as: 2^36/2 = 2^18 = 262144

Unless I’m missing something since it’s early this equation is wrong. When stacking exponents like that you multiply the exponents. So 2^(6*2*1*4*4) =2^192. A square root is also x^(1/2). Multiply the exponents again you get 2^(192/2) =2^(96) = 7.9e28. So a very large number like you said.

Edit: someone pointed out that it should be interpreted as each exponent raised to the next instead of the entire base term in which case the equation does check out. 2^(6^2) instead of (2^6)^2

Anything after the 1 can be ignored as 1 to any power is 1.And you can ignore the 1 because anything to the power 1 is itself

So it’s the square root of 2^6^2. or 2^36

square root of 2^36 is 2 ^18 so yes – 262144
