integral of ((4+sqrt(x)))/(x^3)

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

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

Solution steps

\int \frac{4 + x}{x ^{3}} d x

Expand

\frac{4 + x}{x ^{3}} : \frac{4}{x ^{3}} + \frac{1}{x ^{\frac{5}{2}}}

= \int \frac{4}{x ^{3}} + \frac{1}{x ^{\frac{5}{2}}} 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 \frac{4}{x ^{3}} d x + \int \frac{1}{x ^{\frac{5}{2}}} d x

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

\int \frac{1}{x ^{\frac{5}{2}}} d x = - \frac{2}{3 x ^{\frac{3}{2}}}

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

Add a constant to the solution

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