Question

please tell the correct answer​

Answer 1

$( \frac{2}{3} )^{3} \times {( \frac{2}{3} )}^{ - 6} = { (\frac{2}{3}) }^{2a - 1} \\ = > {( \frac{2}{3} )}^{3 + ( - 6)} = {( \frac{2}{3} )}^{2a - 1} \\ = > 3 - 6 = 2a - 1 \\ = > 2a - 1 = - 3 \\ = > 2a = - 3 + 1 \\ = > a = - 2 \div 2 \\ = > a = - 1$
