Any number with the power of zero is always going to equal:
a. 1
b. 0
c. the number

Surprise! It turns out that the answer is 1.

Why?!!??!

Notice this pattern when working with powers of 2:
2^0  2^1  2^2  2^3  2^4
 ?      2      4      8     16

Every time we increase the power we multiply by 2. Or reading the pattern backwards, every time we decrease the power we divide by 2. What is 2 divided by 2? It is 1! So 2^0 = 1 to finish the pattern:
2^0  2^1  2^2  2^3  2^4
 1      2      4      8     16

Try it with 3 or with 5 or with any number! You'll see that the pattern holds!

The answer is 0.
if a number has 0 as an exponent then it doesn't exist.
