  1. This is really good, different altough a correct answer. Thanks.
  2. Yes, you are right, I couldn´t figure out e^2lnx at first. x^2=2x^3 is the simplified equation. x^2-2x^3=0 x=0 or 1/2. But since ln is not defined for x=0, the answer is x=1/2. Anyway, thanks!
  3. Thanks. I´ll try to work from here. I´ll be back with the result.
  4. Would like some help with an equation. f(x)=e^2x g(x)=lnx The equation is: f(g(x))=g(f(x^3)). f(g(x))=e^2lnx and g(f(x^3))=ln(e^(2x^3) e^2lnx=ln(e^(2x^3) I´m stuck now. I don´t know how to continue to simplify further than this. Would like a hint or a tip so I can proceed.
