Though I know that the limit as x approaches 0 of x^x is 1, I can't prove it...

...can anyone please help me?

Hello marshmellow
certainly you will succeed in proving that the limit for x^x is 1 while x tends to 0.
But remember, this doesn't prove that 0^0 = 1 and most certainly not the uniqueness of 0^0 as limit of x^y while both x and y tend to 0.
