exponentiation - Why is X raised to the power of 0 = 1?

So as the topic states, why is 5^0 = 1 and not 5 or 0? Is it only because the other exponential laws wouldn't work if it was not the case?

Answer

$5^0$ is the product of zero $5$s, which is the empty product, and there are plenty of reasons to define that as $1$.
