integral of sqrt(x)*ln^2(x)

\int x \cdot ln^{2} (x) d x

\frac{2}{3} x^{\frac{3}{2}} ln^{2} (x) - \frac{4}{3} (\frac{2}{3} x^{\frac{3}{2}} ln (x) - \frac{4}{9} x^{\frac{3}{2}}) + C

Solution steps

\int x ln^{2} (x) d x

Apply Integration By Parts

= \frac{2}{3} x^{\frac{3}{2}} ln^{2} (x) - \int \frac{4}{3} x^{\frac{1}{2}} ln (x) d x

\int \frac{4}{3} x^{\frac{1}{2}} ln (x) d x = \frac{4}{3} (\frac{2}{3} x^{\frac{3}{2}} ln (x) - \frac{4}{9} x^{\frac{3}{2}})

= \frac{2}{3} x^{\frac{3}{2}} ln^{2} (x) - \frac{4}{3} (\frac{2}{3} x^{\frac{3}{2}} ln (x) - \frac{4}{9} x^{\frac{3}{2}})

Add a constant to the solution

= \frac{2}{3} x^{\frac{3}{2}} ln^{2} (x) - \frac{4}{3} (\frac{2}{3} x^{\frac{3}{2}} ln (x) - \frac{4}{9} x^{\frac{3}{2}}) + C
