Question

(-4)(-4) use an exponent to rewrite the expression

Answer 1

For this case we have the following expression:
 $(-4)(-4)$
 By properties of exponents we have:
 Same basis, the exponents are added.
 We have then:
 $(-4)^{1+1}$
 Then, rewriting the exponent we have:
 $(-4)^{2}$
 Therefore, an exponent to rewrite the expression is:
 2
 Answer:
 $(-4)^{2}$
 an exponent to rewrite the expression is 2.
