If $x$ is any non-zero real number then $x^0 = 1$ .

But, the question is for any real, so when x = 0 then $x^0$ is undefined. So answer is Can't be determined.

Just to expand on this a bit more:

Sal Khan explains why $0^0$ is undefined quite well: https://www.khanacademy.org/math/pre-algebra/pre-algebra-exponents-radicals/pre-algebra-exponents/v/powers-of-zero
