Answer 2

Answer:

$\frac{3}{2}$

Step-by-step explanation:

$(\frac{1}{3}) ^{-5}$ * $(\frac{1}{3} )^{7}$ = $(\frac{1}{3} )^{2x-1}$

=> $(\frac{1}{3} )^{-5+7}$ =  $(\frac{1}{3} )^{2x-1}$

=>  $(\frac{1}{3} )^{2}$ =  $(\frac{1}{3} )^{2x-1}$

=> 2 = 2x - 1

=> 2 + 1  = 2x

=> 3 = 2x

=> x = $\frac{3}{2}$
