integral of (ln(9x))/(x^3)

\int \frac{ln ( 9 x )}{x ^{3}} d x

- \frac{ln ( 9 x )}{2 x ^{2}} - \frac{1}{4 x ^{2}} + C

Solution steps

\int \frac{ln ( 9 x )}{x ^{3}} d x

Apply Integration By Parts

: - \frac{ln ( 9 x )}{2 x ^{2}} - \int - \frac{1}{2 x ^{3}} d x

= - \frac{ln ( 9 x )}{2 x ^{2}} - \int - \frac{1}{2 x ^{3}} d x

\int - \frac{1}{2 x ^{3}} d x = \frac{1}{4 x ^{2}}

= - \frac{ln ( 9 x )}{2 x ^{2}} - \frac{1}{4 x ^{2}}

Add a constant to the solution

= - \frac{ln ( 9 x )}{2 x ^{2}} - \frac{1}{4 x ^{2}} + C

\int \frac{3 x}{x ^{2} - 6 x + 9} d x

\int \frac{2}{x - 9} d x

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

\int \frac{( 3 x - 2 )}{1 - x - 4 x ^{2}} d x

\int \frac{6}{( x + 3 ) ^{2}} d x
