# How do you simplify 8n^-1 and write it using only positive exponents?

See the entire simplification process below:

#### Explanation:

We will use these two rules for exponents to complete this problem:

${x}^{\textcolor{red}{a}} = \frac{1}{x} ^ \textcolor{red}{- a}$

${a}^{\textcolor{red}{1}} = a$

$8 {n}^{\textcolor{red}{- 1}} = \frac{8}{n} ^ \textcolor{red}{- - 1} = \frac{8}{n} ^ \textcolor{red}{1} = \frac{8}{n}$#
