Evaluate the integral using integration by parts with the indicated choices of u and dv. (Use C for the constant of integration.
Aleksandr-060686 [28]

Take

u=\ln x\implies\mathrm du=\dfrac{\mathrm dx}x

\mathrm dv=4x^2\,\mathrm dx\implies v=\dfrac43x^3

Then

\displaystyle\int4x^2\ln x\,\mathrm dx=\frac43x^3\ln x-\frac43\int x^2\,\mathrm dx=\frac43x^3\ln x-\frac49x^3+C

=\boxed{\dfrac49x^3(3\ln x-1)+C}
