Answer:
1
Step-by-step explanation:
Well you could use the exponential identity that:
To determine: 
Which means that it's equal to: 
and since anything to the power of 0 (except 0) is equal to 1, then the value is 1.
But you can also just see that the numerator and denominator are the same exact value, and since dividing something by it self, results in 1, the answer must be 1, which is kind of a proof as to why h^0 = 1.
