Answer 2

Step-by-step explanation:

$\\ \tt{:}\Rrightarrow \left( \frac{5 {}^{ - 7} }{ {5}^{3} } \right) {}^{ - 2} \times \frac{1}{ {5}^{6} } \\ \\ \tt{:}\Rrightarrow ( {5}^{ - 7 - 3} ) {}^{ - 2} \times \frac{1}{5 {}^{6 } } \\ \\ \tt{:}\Rrightarrow ( {5}^{ - 10} ) {}^{ - 2} \times \frac{1}{ {5}^{6} } \\ \\ \tt{:}\Rrightarrow {5}^{( - 10)( - 2)} \times \frac{1}{5 {}^{6} } \\ \\ \tt{:}\Rrightarrow {5}^{ - 20} \times \frac{1}{ {5}^{6} } \\ \\ \tt{:}\Rrightarrow {5}^{ - 20} \times 5 {}^{ - 6} \\ \\ \tt{:}\Rrightarrow 5 {}^{ - 20 + ( - 6)} \\ \\ \tt{:}\Rrightarrow 5 {}^{ - 20 - 6} \\ \\ \tt{:}\Rrightarrow 5 {}^{ - 26}$
