integral of (x^5)/(\sqrt[3]{x^6+4)}

\frac{1}{4} (x^{6} + 4)^{\frac{2}{3}} + C

Solution steps

Apply u-substitution

Take the constant out:

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

Apply the Power Rule

= \frac{1}{6} \cdot \frac{3}{2} u^{\frac{2}{3}}

Substitute back

u = x^{6} + 4

= \frac{1}{6} \cdot \frac{3}{2} (x^{6} + 4)^{\frac{2}{3}}

Simplify

\frac{1}{6} \cdot \frac{3}{2} (x^{6} + 4)^{\frac{2}{3}} : \frac{1}{4} (x^{6} + 4)^{\frac{2}{3}}

= \frac{1}{4} (x^{6} + 4)^{\frac{2}{3}}

Add a constant to the solution

= \frac{1}{4} (x^{6} + 4)^{\frac{2}{3}} + C
