Evaluating Exponents with Negative Bases:
Ex1 (-2)4 = (-2)(-2)(-2)(-2) = 16
Ex2 -24 = -2(2)(2)(2) = -16
The negative is included within the parenthesis. Expand the negative.
The negative is NOT included within the parenthesis. Expand the 2 ONLY, then attach the negative at then end.
Evaluating Exponents with Negative Bases:
Ex3 (-5)3 = (-5)(-5)(-5) = -125
Ex4 -53 = -5(5)(5) = -125
The negative is included within the parenthesis. Expand the negative.
The negative is NOT included within the parenthesis. Expand the 5 ONLY, then attach the negative at then end.
