Question

(4/3)^-4 × (4/3)^-5 =(4/5)^-3x solve for x

Answer 1

I think this may be the answer

Answer 2

Ans.

$( \frac{4}{3} )^{ - 4} \times( \frac{4}{3} )^{ - 5} = ( \frac{4}{3} )^{ - 3x} \\ or \: \: ( \frac{4}{3} )^{ - 9} = ( \frac{4}{3} )^{ - 3x} \\ ( \frac{4}{3} )^{ - 3.3} = ( \frac{4}{3} )^{ - 3x}$

Now, comparing both sided, we get x = 3.

I HOPE THAT THIS HELPS YOU.
