integral of x^{13}ln(9x^7)

\int x^{13} ln (9 x^{7}) d x

\frac{1}{14} x^{14} (2 ln (3) + 7 ln (x)) - \frac{x ^{14}}{28} + C

Solution steps

\int x^{13} ln (9 x^{7}) d x

Apply Integration By Parts

: \frac{1}{14} x^{14} ln (9 x^{7}) - \int \frac{x ^{13}}{2} d x

= \frac{1}{14} x^{14} ln (9 x^{7}) - \int \frac{x ^{13}}{2} d x

\int \frac{x ^{13}}{2} d x = \frac{x ^{14}}{28}

= \frac{1}{14} x^{14} ln (9 x^{7}) - \frac{x ^{14}}{28}

\frac{1}{14} x^{14} ln (9 x^{7}) = \frac{1}{14} x^{14} (2 ln (3) + 7 ln (x))

= \frac{1}{14} x^{14} (2 ln (3) + 7 ln (x)) - \frac{x ^{14}}{28}

Add a constant to the solution

= \frac{1}{14} x^{14} (2 ln (3) + 7 ln (x)) - \frac{x ^{14}}{28} + C

\int 5 x e^{4 x^{2}} d x

\int \frac{( x ^{3} + 5 x ^{2} - 4 )}{x ^{2}} d x

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

\int cos^{3} (x) - sin^{3} (x) d x

\int x^{9} ln (6 x) d x
