Answer 1

take the derivative of the function

Answer 2

then sub ln(x) into it

what exactly are you have a problem with?

Answer 3

do you know how to take derivatives? Some feed back would be nice

Answer 4

I keep getting 2lnx+2, but I'm hearing the answer is supposed to be (2lnx+2)/x

Answer 5

I do know how to solve for derivatives, but I'm not sure what I'm doing wrong

Answer 6

you are right the answer is 2lnx + 2
