3 AnswersMathematics1 decade agof(x)=ln(4x+8/3x-9)^1/2 ....Find f'(x)?
so the problem is asking for the derivative of ln of the square root of (4x+8 divided by 3x-9)
-i think it is probably easier to solve this using the basic rules for ln, like ln(4x+8/3x-9) is the same as ln(4x+8)-ln(3x-9), and also that ln(x)^1/2=1/2ln(x)...but I still can't figure it out!!
Thanks!
