Answer:  2

Step-by-step explanation:

3 ln (2) + ln (8) = 2 ln (4x)

  ln (2)³ + ln (8) =   ln (4x)²

  ln (2³ · 8)        =   ln (4x)²

      (2³ · 8)        =      (4x)²    

           64         =      16x²

            4          =          x²

           ±2        =           x

-2 is an extraneous solution because x > 0

The only valid answer is x = 2
