Homework Help: Calculus/Logarithms

Posted by Amy on Monday, June 29, 2009 at 8:21pm.

Find the derivative of f(x) = (square root of x)(ln x).

Using my notes, I came up with f'(x) = (1/2*square root of x)/x

The answer in the back of the book says f'(x) = (2+ln x)/(2*square root of x).

Can someone please explain how? Thanks.
