Well, makes sense, does it not? If it also follows that . One x multiplied together (so to speak) is just x.

Similar logic applies to . Zero x's multiplied together is obviously 0. [EDIT: Wow, I've handled x^0 enough times you'd think I wouldn't mess this up! x^0 = 1 as explained below. Let that be a lesson to me!]

Do note that 0^0 is a little tougher to settle. Why? An explanation can be found here:
