Question

Find the value of x:
Use the above question​

Answer 1

Answer:

x = (-5)

Step-by-step explanation:

$(\frac{4}{3} )^{(-5)+(-4)} = (\frac{3}{4} )^{-2x-1} \\\\(\frac{4}{3} )^{-9} = (\frac{3}{4} )^{-2x-1}$

to make base same on both side we will reciprocal L.H.S as per question

$(\frac{3}{4} )^{9} = (\frac{3}{4} )^{-2x-1}$

comparing both side as base is equal

So,

9 = -2x-1

9+1 = (-2x)

10 = (-2x)

-10/2 = x

x = (-5)
