Answer 1

${ (\frac{7}{5}) }^{ - 5} \times { (\frac{5}{7} }^{3})$

${ (\frac{5}{7}) }^{ 5} \times { (\frac{5}{7} }^{3})$

${ (\frac{7}{5}) }^{ 5 + 3}$

${ (\frac{7}{5}) }^{ 8} = x$

${x}^{5} = { { (\frac{7}{5}) }^{ (8)} }^{5}$

$= { (\frac{7}{5}) }^{ 8 \times 5}$

$= { (\frac{7}{5}) }^{ 40}$

Answer is D
