Hey friend,
Here is the answer you were looking for:
$( {( \frac{15}{19}) }^{ - 4} )^{ - 20} \\ \\ ( {( \frac{19}{15}) }^{4} )^{ - 20} \\ \\ by \: using \: the \: identity \\ {( {a}^{m}) }^{n} = {a}^{m \times n} \\ \\ = {( \frac{19}{15}) }^{4 \times - 20} \\ \\ = (\frac{19}{15} )^{ - 80} \\ \\ = ({ \frac{15}{19}}) ^{80}$

Hope this helps!!!!!
