21. 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.

22. 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.

23. Exponents of Zero
Anything Raised to Zero = 1.
Ex5 20
= 1 Ex6 (-2)0
= 1
Ex7 -20
= -1 Ex8 x0
= 1
Notice this answer is -1, not just 1. This
is because the negative on the base of 2
is NOT being raised to the zero power.
