integral of (4x)/(\sqrt[5]{x^2+2)}

\frac{5}{2} (x^{2} + 2)^{\frac{4}{5}} + C

Solution steps

Take the constant out:

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

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

= 4 \cdot \frac{1}{2} \cdot \frac{5}{4} u^{\frac{4}{5}}

Substitute back

u = x^{2} + 2

= 4 \cdot \frac{1}{2} \cdot \frac{5}{4} (x^{2} + 2)^{\frac{4}{5}}

Simplify

4 \cdot \frac{1}{2} \cdot \frac{5}{4} (x^{2} + 2)^{\frac{4}{5}} : \frac{5}{2} (x^{2} + 2)^{\frac{4}{5}}

= \frac{5}{2} (x^{2} + 2)^{\frac{4}{5}}

Add a constant to the solution

= \frac{5}{2} (x^{2} + 2)^{\frac{4}{5}} + C
