Answer 2

d/dx lnx is 1/x

Answer 3

but what do I do with the x^5 in the denominator?

Answer 4

[f(x)/g(x)]' = \[\frac{ g(x)*f(x)'-f(x)*g(x)' }{ [g(x)]^2 }\]

Answer 5

your f(x) =ln x; your g(x) =x^5

Answer 6

ah, I thought I could maneuver it without the quotient rule, I guess not. Thanks

Answer 7

ok. take your time.
