integral from 1 to 8 of 4x^{1/3}

\int_{1}^{8} 4 x^{\frac{1}{3}} d x

45

Solution steps

\int_{1}^{8} 4 x^{\frac{1}{3}} d x

Take the constant out:

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

= 4 \cdot \int_{1}^{8} x^{\frac{1}{3}} d x

Apply the Power Rule

= 4 [\frac{3}{4} x^{\frac{4}{3}}]_{1}^{8}

Compute the boundaries:

\frac{45}{4}

= 4 \cdot \frac{45}{4}

Simplify

= 45
