integral of x^3+1/(x^5)

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

\frac{x ^{4}}{4} - \frac{1}{4 x ^{4}} + C

Solution steps

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

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

\int \frac{1}{x ^{5}} d x = - \frac{1}{4 x ^{4}}

= \frac{x ^{4}}{4} - \frac{1}{4 x ^{4}}

Add a constant to the solution

= \frac{x ^{4}}{4} - \frac{1}{4 x ^{4}} + C
