The equation `(3e)^(4x) - 6 = 18` has to be solved for x.

`(3e)^(4x) - 6 = 18`

=> `(3e)^(4x) = 24`

take the natural log of both the sides

=> `4x*ln(3*e) = ln 24`

=> `4x*(ln 3 + ln e) = ln 24`

=> `4x*(1 + ln 3) = ln 24`

=> `x = (ln 24)/(4*(1+ln 3))`

=> `x ~~ 0.3785`

The solution of the equation is `x ~~ 0.38`
