Answer 2

Solution :-

${ (\frac{5}{6} ) }^{7} \times { (\frac{5}{6}) }^{ - 9} = { (\frac{5}{6}) }^{2x} \\ \\ \red{ \mathfrak{using \: {a}^{m} \times {a}^{n} = {a}^{m + n} }} \\ \\ { (\frac{5}{6} )}^{7 - 9} = {( \frac{5}{6}) }^{2x} \\ \\ {(\frac{5}{6} )}^{ - 2} = { (\frac{5}{6}) }^{2x} \\ \\ \pink{ \mathfrak{on \: comparing \: exponentially}} \\ - 2 = 2x \\ x = \frac{ - 2}{2} \\ \implies { \tt{ x = - 1}}$
