Question

{11/9}^3×{9/11}^6={11/9}^2x-1​

Answer 1

Answer:

$(\frac{11}{9} )^{3} \times (\frac{9}{11} )^{6} = (\frac{11}{9} )^{2x - 1} \\ \\ = > (\frac{11}{9} )^{3} \times (\frac{11}{9} ) ^{ - 6} = (\frac{11}{9} ) ^{2x - 1} \\ \\ \\ \\ = > 2x - 1 = 3 - 6 \\ \\ = > 2x = - 3 + 1 \\ \\ \\ = > 2x = - 2 \\ \\ x = - 1$
