Question

Find f'(x) if f(x) = ln((4x+9)/(5x-7))^(1/2)

Answer 1

Do you do U' over U?

Answer 2

Anyone?

Answer 3

\[\frac{ \ln (4x+9) }{ \sqrt{5x-7} }\]
This is the problem? :D

Answer 4

ln of (4x+9)/(5x-7) all square rooted :D

Answer 5

So the 4x+9 is raised to the power of 1/2 as well.

Answer 6

kk :)
So your OUTERMOST function is Natural Log, so You'll take the derivative of the natural log, then we'll have a nasty chain rule inside of there ^^
