# How do you simplify (b^7)^2 and write it using only positive exponents?

${\left({x}^{\textcolor{red}{a}}\right)}^{\textcolor{b l u e}{b}} = {x}^{\textcolor{red}{a} \times \textcolor{b l u e}{b}}$
${\left({b}^{\textcolor{red}{7}}\right)}^{\textcolor{b l u e}{2}} = {b}^{\textcolor{red}{7} \times \textcolor{b l u e}{2}} = {b}^{14}$
