integral of x/(\sqrt[3]{x^2-8)}

\frac{3}{4} (x^{2} - 8)^{\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{3}{2} u^{\frac{2}{3}}

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

Substitute back

u = x^{2} - 8

= \frac{1}{2} \cdot \frac{3}{2} (x^{2} - 8)^{\frac{2}{3}}

Simplify

\frac{1}{2} \cdot \frac{3}{2} (x^{2} - 8)^{\frac{2}{3}} : \frac{3}{4} (x^{2} - 8)^{\frac{2}{3}}

= \frac{3}{4} (x^{2} - 8)^{\frac{2}{3}}

Add a constant to the solution

= \frac{3}{4} (x^{2} - 8)^{\frac{2}{3}} + C

\int \frac{4}{x ^{2} + 16} d x

f (v) = (v^{- 3} + 6 v^{- 2})^{3}

f (x) = \frac{3}{x + 1}

\frac{\partial}{\partial z} (x y cos (x + yz))

\frac{d y}{d x} = 20 - 5 y
