Answer 2

${ (\frac{7}{11} ) }^{2m} \times {( \frac{11}{7} )}^{4} ={ (\frac{49}{121} ) }^{ - 3} \\ = > { (\frac{7}{11}) }^{2m} \times {( \frac{7}{11}) }^{ - 4} = ({ \frac{7}{11} )}^{2 \times ( - 3)} \\ = > \: {( \frac{7}{11} ) }^{2m - 4} = {( \frac{7}{11}) }^{ - 6} \\ base \: are \: same \: then \\ 2m - 4 = - 6 \\ = > 2m = - 6 + 4 \\ = - 2 \\ = > m = \frac{ - 2}{2} = - 1$
