Any number to the zero power always gives one.

One rule for exponents is that exponents add when you have the same base. So if you have a number, x, and exponents, a and b, then:

xa * xb = x(a+b)

So then if we make one of the exponents negative:

xa * x-b = x(a-b)

And if the exponents are the same magnitude (a = b)xa * x-b = xa * x-a = x(a-a) = x0
