integral of x^7ln(8x)

\int x^{7} ln (8 x) d x

\frac{1}{8} x^{8} ln (8 x) - \frac{x ^{8}}{64} + C

Solution steps

\int x^{7} ln (8 x) d x

Apply Integration By Parts

: \frac{1}{8} x^{8} ln (8 x) - \int \frac{x ^{7}}{8} d x

= \frac{1}{8} x^{8} ln (8 x) - \int \frac{x ^{7}}{8} d x

\int \frac{x ^{7}}{8} d x = \frac{x ^{8}}{64}

= \frac{1}{8} x^{8} ln (8 x) - \frac{x ^{8}}{64}

Add a constant to the solution

= \frac{1}{8} x^{8} ln (8 x) - \frac{x ^{8}}{64} + C

\int 6 cos (x) cos (sin (x)) d x

\int \frac{( x ^{2} + 13 )}{x ^{2} + 16} d x

\int 4 x e^{8 x^{2}} d x

\int (x - 4) (- 2 x + 7) d x

\frac{1}{1 - x}
