Answer 2

Do you know how to do implicit differentiation? And do you know your laws of logarithms?

Answer 3

yes

Answer 4

i struggle logs though

Answer 5

So the laws of logarithms are:
\[1. log(b^c)=clog(b) \]
\[2. log(bc)=log(b)+log(c)\]

Answer 6

Okay, so when it asks for you to do logarithmic differentiation, it is essentially asking you to take log of both sides, and then implicitly differentiate what you get.

Answer 7

So do you know how to start?

Answer 8

no :/

Answer 9

Lol, log both sides. For example, if y=x^4, then to log both sides means:
log(y)=log(x^4)
