Answer 1

The rule is \[\frac{ d }{ dx } \ln|x| = \frac{ 1 }{ x }\]

Answer 2

what are the next steps?

Answer 3

Use the Quotient Rule

Answer 4

I don't think that is the formula I used

Answer 5

The answer is y=(1-7lnx)/(x^8)

Answer 6

you are not deriving both functions twice in a quotient rule.

Answer 7

Ohh yes you're right. :$ sorry

Answer 8

Elaborate please
