Find the co ordinates of the turning point of the curve

$\displaystyle y = e^2^x - 3e^x$

and determine whether this point is a local max or local min.

I've differentiated this and put it = to 0 and got

$\displaystyle 2e^2^x - 3e^x$ is that right? In the answer it says that x is loge^3/2 how do I change the e to log?

Thanks
