Math question: If I raise 2 to the power of X, where X is a whole number, and subtract 8, what is the result when X is square rooted and then squared again?

Raising the number 2 to the power of 256 equals an extremely large value. Subtracting 8 from this result is negligible compared to the original value. Therefore, the result of taking the square root of this value and then squaring it again would still yield the original value. Thus, the answer is approximately equal to 2 raised to the power of 256 again.

Math question: If you take the square root of 256 and then multiply it by 4, what is the result?

To solve this, we first find the square root of 256, which equals 16. Multiplying 16 by 4 gives us 64. Therefore, the result of multiplying the square root of 256 by 4 is 64.

Math question: What is the square root of 256?

The square root of 256 is 16. In mathematics, the square root of a number is a value that, when multiplied by itself, gives the original number. Thus, multiplying 16 by itself results in 256.
