Question

\left (\frac{n^{-{4}}}{4 m^{-{5}}}\right )^{-{2}} \cdot 6 n^{6} m^{2}

Answer 1

$\left(\frac{4m^{-{5}}}{n^{-{4}}}\right )^{{2}} \cdot 6 n^{6} m^{2}=\left\frac{16m^{-{10}}}{n^{-{8}}}\right \cdot 6 n^{6} m^{2}= 16m^{-10} * 6n^{14}m^{2} =$$96* \frac{1}{ m^{8} } * n^{14} = \frac{ 96n^{14} }{ m^{8} }$
