Hi Mirolala
This is a difficult log question you have here

You must be able to do at least something with it.
You will need to split the log(8x) up. Using log identities

http://en.wikipedia.org/wiki/List_of_logarithmic_identities
this might be useful if you have forgotten them.

Take all the terms with x onto one side and the rest on the other side of the equal sign.
And go from there
I got x=(e 5)/2
but I will admit I did it quickly and I haven't checked the answer.
