He posted the answer, not the full solution. It's incorrect anyway.
2(e^3x+1)=10 is not the same as 2(e^(3x+1))=10

Well, that's down to the OP, seeing as he's left it quite ambiguous. However, TSR isn't a place where we just 'give' answers to questions, in essence, the answer is the 'full' solution, it leaves nothing for the OP to do, which is precisely what we don't want. Don't be a smart arse.

As usual

2:2(e^3x+1)=10:2 we have divided the equation with 2 cos we want to find inside()
e^3x+1=5 e^3x=4 using ln=loge function for 2 side of equation
lne^3x=ln4 3x=ln4 x=ln4^3

x=ln4^3


Posting full solutions is against the rules, even when they are incorrect
