Given that , find the all values of in .
One possibility is that the bases are the same. If that is the case, then and the exponent is . Since the base is an even number, we can use the positive and negative value of the base: .
Another possibility is that the exponent is equal to 0, because any non-zero real number raised to the power of 0 is equal to 1: . If that is the case, then , so . It does not matter if the bases are different when the exponents are 0.
Therefore, the values of in are and .
