i use the laws of exponents a lot, but today, i found myself asking the question "why?", STUPID JAVA and yahoo chat were being very fickle loading. So it brought me here, to the, really, smart people.

using the number 5 as an example:

5^2 = 5x5 (or is it?)

5^1 = 5x1 (?)

so what is

5^0 = ?? = 1 (?)

so my question is, why is x^n = 1 (where x not equal to zero) ?
