integral of x^8*ln(x)

integral

x^{8} \cdot ln (x)

\frac{1}{9} x^{9} ln (x) - \frac{x ^{9}}{81} + C

Solution steps

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

Apply Integration By Parts

: \frac{1}{9} x^{9} ln (x) - \int \frac{x ^{8}}{9} d x

= \frac{1}{9} x^{9} ln (x) - \int \frac{x ^{8}}{9} d x

\int \frac{x ^{8}}{9} d x = \frac{x ^{9}}{81}

= \frac{1}{9} x^{9} ln (x) - \frac{x ^{9}}{81}

Add a constant to the solution

= \frac{1}{9} x^{9} ln (x) - \frac{x ^{9}}{81} + C

\frac{x}{( 1 + x ) ^{2}}

\frac{1}{e ^{- x}}

- tan^{2} (x)

\frac{1}{sec ( x )}

\frac{1}{( x ^{2} - x )}
