Answer 2

HELLO DEAR,


${ (\frac{9}{4}) }^{x} \times { \frac{8}{27} }^{x - 1} = \frac{2}{3} \\ \\ = > {( \frac{2}{3} )}^{ - 2x} \times {( \frac{2}{3} )}^{3(x - 1)} = \frac{2}{3} \\ \\ = { (\frac{2}{3} )}^{ - 2x + 3x - 3} = \frac{2}{3} \\ \\ = > x - 3 = 1 \\ \\ = > x = 4$



I HOPE ITS HELP YOU DEAR,
THANKS
