Answer:

Step-by-step explanation:          

                                                                                       1

Given x³, we can write the equivalent expression -----------

                                                                                    x^(-3)

                                                              1

Given y^(-4) we can rewrite this as  ----------

                                                             y^4

Here we're applying the "rule of negative exponents."

ANEK [815]

Answer:

She will receive 22% commission

Step-by-step explanation:

18% commission when the profit on a car is under $400

lukranit [14]

Notice that the denominator is a multiplied by 2 for each fraction.

1/1•2 = 1/2

1 /2•2 = 1/4

1/4•2 = 1/8

1/8•2 = 1/16

1/16•2 =1/32

The next size is 1/32.
