Hello!

\int \sf \dfrac{\sf log\:x}{\sf x}.dx

Then,
Differentiate both sides w.r.t. \bf\small{x} :

\dfrac{1}{\sf x} = \dfrac{\sf dt}{\sf dx} \\ \\ \implies \dfrac{1}{\sf x}. \sf dx = dt \\ \\ \implies \int \sf t.dt \implies \dfrac{\sf t^{2}}{2} + \sf C \implies \boxed{\red{\bf{\dfrac{1}{2}(\sf log\:x)^{2} + \sf C}}}

Cheers!

BrainlyWarrior: it's t^2
iHelper: Yes. I have already written t²
BrainlyWarrior: so value will be (logx)^2
iHelper: Yes. What's wrong in it brother?!
