integral of (x^3)/(\sqrt[5]{x^2+5)}

\frac{1}{2} (\frac{5}{9} (x^{2} + 5)^{\frac{9}{5}} - \frac{25}{4} (x^{2} + 5)^{\frac{4}{5}}) + C

Solution steps

Apply u-substitution

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

Expand

Apply the Sum Rule:

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

\int u^{\frac{4}{5}} d u = \frac{5}{9} u^{\frac{9}{5}}

= \frac{1}{2} (\frac{5}{9} u^{\frac{9}{5}} - \frac{25}{4} u^{\frac{4}{5}})

Substitute back

u = x^{2} + 5

= \frac{1}{2} (\frac{5}{9} (x^{2} + 5)^{\frac{9}{5}} - \frac{25}{4} (x^{2} + 5)^{\frac{4}{5}})

Add a constant to the solution

= \frac{1}{2} (\frac{5}{9} (x^{2} + 5)^{\frac{9}{5}} - \frac{25}{4} (x^{2} + 5)^{\frac{4}{5}}) + C

- 3 cos (x)

\int \frac{3 x - 2}{x ^{2} - 6 x + 10} d x

\frac{d}{d x} (1 0^{x l n (x) - x})

\int 2 e^{x} sin (x) d x

x \to 0 lim ((- 3 x + 1)^{\frac{5}{x}})
