integral of (8x+2)^{1/3}

\int (8 x + 2)^{\frac{1}{3}} d x

\frac{3}{32} (8 x + 2)^{\frac{4}{3}} + C

Solution steps

\int (8 x + 2)^{\frac{1}{3}} d x

Apply u-substitution

= \int \frac{u ^{\frac{1}{3}}}{8} d u

Take the constant out:

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

= \frac{1}{8} \cdot \int u^{\frac{1}{3}} d u

Apply the Power Rule

= \frac{1}{8} \cdot \frac{3}{4} u^{\frac{4}{3}}

Substitute back

u = 8 x + 2

= \frac{1}{8} \cdot \frac{3}{4} (8 x + 2)^{\frac{4}{3}}

Simplify

\frac{1}{8} \cdot \frac{3}{4} (8 x + 2)^{\frac{4}{3}} : \frac{3}{32} (8 x + 2)^{\frac{4}{3}}

= \frac{3}{32} (8 x + 2)^{\frac{4}{3}}

Add a constant to the solution

= \frac{3}{32} (8 x + 2)^{\frac{4}{3}} + C

What is the integral of (8x+2)^{1/3} ?
The integral of (8x+2)^{1/3} is 3/32 (8x+2)^{4/3}+C
