integral of x^3log_{2}(x)

\int x^{3} lo g_{2} (x) d x

\frac{1}{4} x^{4} lo g_{2} (x) - \frac{x ^{4}}{16 ln ( 2 )} + C

Solution steps

\int x^{3} lo g_{2} (x) d x

Apply Integration By Parts

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

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

\int \frac{x ^{3}}{4 ln ( 2 )} d x = \frac{x ^{4}}{16 ln ( 2 )}

= \frac{1}{4} x^{4} lo g_{2} (x) - \frac{x ^{4}}{16 ln ( 2 )}

Add a constant to the solution

= \frac{1}{4} x^{4} lo g_{2} (x) - \frac{x ^{4}}{16 ln ( 2 )} + C

\int x tan^{8} (x^{2}) sec^{2} (x^{2}) d x

\int - x sin (y) + sin (y) + y cos (y) d y

\int x^{2} (1 0^{x^{3}}) d x

\int \frac{3 x ^{2} + 1}{( x + 1 ) ( x - 5 ) ^{2}} d x

\int x (x - 8)^{\frac{3}{4}} d x
