Hi guys, I am struggling with this question here:
I have listed my answer (well as close as I have got to the answer) beneath the question, however it is incorrect according to the book. I used the product rule to first derive the numerator to get the equation, (1+lnx)/e^x. I then used the quotient rule to get the answer I have listed in the picture above, but it seems I have made a mistake somewhere. For the quotient rule I had the following values:
u=1+lnx
u'=1/x
v=e^x
v'=e^x
Any help is greatly appreciated
