Easy question.

Now for a hard one...why is anything to the zeroth power equal to one?

It's defined that way. It just fits in with a mathematical frame of reference, without meaning anything per se.

Damn useful though!

Gnomon - time to move on

If you divide x to the power of 5 by x, you get x to the power of 4.
If you divide x to the power of 4 by x, you get x to the power of 3.
If you divide x to the power of 3 by x, you get x to the power of 2.
If you divide x to the power of 2 by x, you get x to the power of 1.
If you divide x to the power of 1 by x, what should you get?

Well we know that x to the power of 1 is x, and x/x = 1, so it makes sense that x to the power of 0 is 1. So we define it that way.
