Question

Differentiate the function.
f(x)=ln(x^7+2)....now this i really got stuck on...i try to take ln on both side but screwed it up

Answer 1

Why take ln on both sides? Just use the chain rule!

Answer 2

no just take it

Answer 3

You need the chain rule (i.e. Dx(f(g(x))=f'(g(x))*g'(x)

Answer 4

use the almighty chain rule this is not "logarithmic differentiation "

Answer 5

let me know when you get
\[\frac{7x^6}{x^7+2}\] and say "is that all?"

Answer 6

ok got it

Answer 7

sometimes after doing hard problems the easy ones are too simple

Answer 8

wait thats it...?

Answer 9

i thought there were more to it
