Fill in the missing number:
To solve this problem, we need to understand how powers with a base of zero work. Typically, for any positive integer , raising zero to that power results in zero, as follows:
Therefore, to satisfy the equation , the exponent should be any positive integer. Hence, the missing number that makes the equation true is simply any positive integer.
Therefore, the correct answer is a (any number), which corresponds to any positive integer number.
