# Thread: F'(x)

1. ## F'(x)

I was wondering if you guys can teach me how to do this problem

the problem is
Find f'(x)
2) f(x) = log(1-x)^2

2. I want to say your answer should be 2*(-1/1-x) so we can say -2/1-x

can say 2log(1-x)

u=1-x then u=-1 then 2*u/u which is what we get above

3. How did you conclude to that

4. my final answer is -2 / (1-x)ln(10). Is that it

You should not have a log in your answer check out this site
5. Derivative of the Logarithmic Function see if this helps you

6. so how would i get rid of it

7. do i just filp it. Man now i am really lost
