# How do you simplify (y^-3)^-4?

${\left({x}^{\textcolor{red}{a}}\right)}^{\textcolor{b l u e}{b}} = {x}^{\textcolor{red}{a} \times \textcolor{b l u e}{b}}$
${\left({y}^{\textcolor{red}{- 3}}\right)}^{\textcolor{b l u e}{- 4}} \implies {y}^{\textcolor{red}{- 3} \times \textcolor{b l u e}{- 4}} \implies {y}^{12}$
