integral of (3sqrt(x)+2/(x^3))

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

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

Solution steps

\int 3 x + \frac{2}{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 3 x d x + \int \frac{2}{x ^{3}} d x

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

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

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

Add a constant to the solution

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