Answer 1

Answer:

$( \frac{4}{3} ) {}^{ - 5} \times (\frac{4}{3} )^{ - 4} =( \frac{3}{4} )^{ - 2x - 1} \\ \\ = >( \frac{4}{3} ) ^{ - 5 + ( - 4)} = (\frac{3}{4} ) ^{ - 2x - 1} \\ \\ = > ( \frac{4}{3} ) {}^{ - 9} = ( \frac{3}{4} ) {}^{ - 2 x - 1 } \\ \\ \\ = > \frac{1}{ (\frac{4}{3} ) ^{9} } =( \frac{3}{4})^{ - 2x - 1} \\ \\ \\ \\ = > (\frac{3}{4} ) ^{9} = (\frac{3}{4} ) ^{ - 2x - 1} \\ \\ \\ \\ \\ = = > > 9 = - 2x - 1 \\ \\ \\ = = > > 10 = - 2x \\ \\ \\ x = - 5$
