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

Answer 1

Here.

If 2^4 = 2x2x2x2 =16.
Then 2^3 = 16/2 = 2x2x2x2/2 = 2x2x2 = 8.
And 2^2 = 8/2 = 2x2x2/2 = 2×2 = 4.
So 2^1 = 4/2 = 2×2/2 = 2
So 2^0 = 2/2 = 1.

And that’s why 2^-1 = 1/2
And 2^-2 = 1/(2×2) = 1/4.
