integral from 0 to 8 of 2pix(x^{2/3})

\int_{0}^{8} 2 π x (x^{\frac{2}{3}}) d x

192 π

Decimal

603.18578 \dots

Solution steps

\int_{0}^{8} 2 π x x^{\frac{2}{3}} d x

Take the constant out:

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

= 2 π \cdot \int_{0}^{8} x x^{\frac{2}{3}} d x

Simplify

x x^{\frac{2}{3}} : x^{\frac{5}{3}}

= 2 π \cdot \int_{0}^{8} x^{\frac{5}{3}} d x

Apply the Power Rule

= 2 π [\frac{3}{8} x^{\frac{8}{3}}]_{0}^{8}

Compute the boundaries:

96

= 2 π 96

Simplify

= 192 π
