8-47.

Rewrite each of the expressions below in a simpler form using exponents.

1. $4 · 4 · 5 · 5 · 5$

Notice how many 4's there are and how many 5's there are. The exponent refers to how many times a number is multiplied by itself.

Since there are two 4's and three 5's:

$4^{2} · 5^{3}$

1. $3 · 3 · 3 · 3 · 3 · y · y$

Use the same method as in (a).

1. $(6x)(6x)(6x)(6x)$

Use the same method as in (a).

$\left(6x\right)^{4}$
