# How do you simplify 6m^-4n^-2 and write it using only positive exponents?

Use this rule for exponents: ${x}^{\textcolor{red}{a}} = \frac{1}{x} ^ \textcolor{red}{- a}$
$6 {m}^{\textcolor{red}{- 4}} {n}^{\textcolor{red}{- 2}} = \frac{6}{{m}^{\textcolor{red}{- - 4}} {n}^{\textcolor{red}{- - 2}}} = \frac{6}{{m}^{\textcolor{red}{4}} {n}^{\textcolor{red}{2}}}$
