This is the question and the answer, but I don't understand it.
With an exponent of ^2 it's a simple matter -3(-2)^2 = -3(4). But the problem below has both a negative exponent and an exponent less than 2. Can someone help me understand first how a negative exponent effects a problem and then how an exponent of less than 2 effects a problem? Thanks.
-3(-2)^-1 = -(3/-2)
-3 * (a)^(-1) = -3/a
Let a = -2
-3 * (-2)^(-1) = -3/(-2) = +3/2
