Is this the answer to derivative problem?

Question

I have to find derivative of : (ln x)^2

I got 2x but i dont think i did anything with ln

Answer 1

y = (ln x)^2
let u = ln x
du/dx = d/dx (ln x) = 1/x

y = u^2
dy/du = d/du (u^2) = 2u = 2 ln x

dy/dx = dy/du * du/dx
= 2 ln x * 1/x
= 2/x * ln x

Answer 2

lnx^2
=2/x

rule: y=ln x^n
dy/dx= n/x

Answer 3

anti spinoff is merely the different of spinoff meaning merely the different of differentiation. for the above situation upload a million and subtract a million in the numerator x+a million-a million/x+a million wish you spotted that the cost doesnt exchange now (x+a million)-a million/x+a million now placing apart a million - a million/x+a million now it turns into less demanding essential of a relentless ithink u comprehend and essential of a million/x+a million is log(a million/x+a million) so the respond would be x-log(a million/x+a million)

Answer 4

(2*ln x)/x

Answer 5

Answer:
{d((lnx)^2)/d(lnx)}* {d(lnx)/dx}
= 2*{ln(x)}/x

Answer 6

d{(ln x)²}/dx = (2ln x)/x
