I am not sure how to approach this...I have to find the value of x that makes the derivate of f(x) equal to zero...here's what I have so far (is it correct?) and how is the problem finished?

Thank you very much!

f(x) = (1/x) + ln(x)

f'(X) = ln|x| + (1/x)

0 = ln|x| + (1/x)

how do I solve for x??

Thanks again :)
