integral of 3x^5+x^2ln(x)

\int 3 x^{5} + x^{2} ln (x) d x

\frac{x ^{6}}{2} + \frac{1}{3} x^{3} ln (x) - \frac{x ^{3}}{9} + C

Solution steps

\int 3 x^{5} + x^{2} ln (x) d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 3 x^{5} d x + \int x^{2} ln (x) d x

\int 3 x^{5} d x = \frac{x ^{6}}{2}

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

= \frac{x ^{6}}{2} + \frac{1}{3} x^{3} ln (x) - \frac{x ^{3}}{9}

Add a constant to the solution

= \frac{x ^{6}}{2} + \frac{1}{3} x^{3} ln (x) - \frac{x ^{3}}{9} + C

\int \frac{X ^{2}}{X ( X ^{2} - 9 )} d X

\int csc^{2} (6 x) cot (6 x) d x

\int e^{5 x} (e^{5 x} + 2)^{7} d x

\int \frac{x ^{2}}{x ^{2} + 6} d x

\int 2 x + ln (x) d x
