integral from 0 to 1 of x^7(1+x^8)^7

\int_{0}^{1} x^{7} (1 + x^{8})^{7} d x

\frac{255}{64}

Decimal

3.984375

Solution steps

\int_{0}^{1} x^{7} (1 + x^{8})^{7} d x

Apply u-substitution

= \int_{1}^{2} \frac{u ^{7}}{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_{1}^{2} u^{7} d u

Apply the Power Rule

= \frac{1}{8} [\frac{u ^{8}}{8}]_{1}^{2}

Compute the boundaries:

\frac{255}{8}

= \frac{1}{8} \cdot \frac{255}{8}

Simplify

= \frac{255}{64}
