ELI5, how does 2^0 power equal 1?

Question

I’m doing my GED and passed that math part but this never came up. I saw it on a meme and am lost.
Help!!??

Answer 1

Another helpful way to think about it:

2^2 = 2 * 2 * 1

2^1 = 2 * 1

2 ^ 0 = 1

2^(-1) = 1/2

2^(-2) = 1 / 2 / 2 = (1/2)^2 = (1^2 )/(2^2 ) = 1/2^2
