what if somthing is to the0 power

Anything to the 0 power is 1

any number to the zeroth power is = to 1.  you can think of this (except for 0 to the zeroth power) as taking higher and higher roots of a number until the root gets very large...and this will always approach 1.  example: 2^0 =1;  think of 2^0.5 = 1.414..., 2^0.25 = 1.189, 2^0.1 = 1.07177..  as you can see you're heading towards 1 pretty fast.  This also works for negative numbers.   Now, the proof that 0^0 = 1 is much more involved and won't be covered here...just take it as a definition for now.

0 is 1
