integral of x^5ln(3x^3)

\int x^{5} ln (3 x^{3}) d x

\frac{1}{6} x^{6} (ln (3) + 3 ln (x)) - \frac{x ^{6}}{12} + C

Solution steps

\int x^{5} ln (3 x^{3}) d x

Apply Integration By Parts

: \frac{1}{6} x^{6} ln (3 x^{3}) - \int \frac{x ^{5}}{2} d x

= \frac{1}{6} x^{6} ln (3 x^{3}) - \int \frac{x ^{5}}{2} d x

\int \frac{x ^{5}}{2} d x = \frac{x ^{6}}{12}

= \frac{1}{6} x^{6} ln (3 x^{3}) - \frac{x ^{6}}{12}

Simplify

ln (3 x^{3}) : 3 ln (x) + ln (3)

= \frac{1}{6} x^{6} (ln (3) + 3 ln (x)) - \frac{x ^{6}}{12}

Add a constant to the solution

= \frac{1}{6} x^{6} (ln (3) + 3 ln (x)) - \frac{x ^{6}}{12} + C

\int \frac{10}{x ^{6}} d x

\int \frac{1}{4 x - 5} d x

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

\int \frac{e ^{- x}}{1 + x} d x

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