How Do I Solve This Equation With Ln?
I'm revising for exam and I can't remember how to do this type of questions.
Solve 2lnx = 3ln2
I've gone as far as this lnx = 3ln2/2 and then it's a total blank!!!

Remember the basic log rule, that alog b = log b^a
So, if 2lnx = 3ln2, then ln x^2 =ln 2^3
Then, x^2 = 2^3
x = sqrt 8, or 2 * sqrt 2
