(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find the derivative of f(x):

f(x)= 1/ ((ln(x)^2))

2. Relevant equations

f(x)= ln(x)

f'(x)= 1/((ln(x))

3. The attempt at a solution

Dx(1/ln(x)^2) =

Dx((ln(x))^-2)=

-2*(ln(x)^-3) * Dx(ln(x)) =

-2*(ln(x)^-3) * 1/x =

-2/(x*ln(x)^3)

Are these the correct steps? I'm getting myself confused
