How to enter a problem with negative base and even power?

Correct input: (-3)^2. Here the minus sign is "under " the square, you need to multiply negative 3 by itself and that is why the result is positive: (-3)^2= (-3)*(-3) = 9

Incorrect input: -3^2. In this case the minus sign is in front of the power, and therefore it is left out from the calculation, then you multiply two positive numbers and add a minus to the result: -3^2 = -(3)*(3) = -9
