integral of (5x^2+7sqrt(x)+1/(x^3))

\int (5 x^{2} + 7 x + \frac{1}{x ^{3}}) d x

\frac{5 x ^{3}}{3} + \frac{14}{3} x^{\frac{3}{2}} - \frac{1}{2 x ^{2}} + C

Solution steps

\int 5 x^{2} + 7 x + \frac{1}{x ^{3}} 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 5 x^{2} d x + \int 7 x d x + \int \frac{1}{x ^{3}} d x

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

\int 7 x d x = \frac{14}{3} x^{\frac{3}{2}}

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

= \frac{5 x ^{3}}{3} + \frac{14}{3} x^{\frac{3}{2}} - \frac{1}{2 x ^{2}}

Add a constant to the solution

= \frac{5 x ^{3}}{3} + \frac{14}{3} x^{\frac{3}{2}} - \frac{1}{2 x ^{2}} + C

\int x^{9} ln (3 x^{5}) d x

\int \frac{3 x + 7}{x ^{2} + 6 x + 25} d x

\int sin (2 + x) d x

\int sec^{1} (x) d x

\int (8 - 2 x)^{9} d x
