When you enter that it is trying to find the square root of 9, since any number to the power of a fraction is the equivalent to a root. The square root of 9 is 3.

1/2 is same as√ hence √9 = 3.0

Yes it is, for example if you did 9**(1/3), it would find the cube root.

in python 9**(1/2) will be 1 and not 3 because you're dividing integer/integer so answer Will be an integer. 1/2 is 0 so 9**0 is 1. correct question is why 9**(1/2.0) is 3.0
