# How do you simplify 2v^-3 and write it using only positive exponents?

Dec 21, 2016

$\frac{2}{v} ^ 3$

#### Explanation:

One of the rules for exponents is:

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

Us this rule on the problem gives:

$2 {v}^{-} 3 = \frac{2}{v} ^ \left(- \left(- 3\right)\right) = \frac{2}{v} ^ 3$
