integral from 0 to 1 of x^8(1+2x^9)^5

\int_{0}^{1} x^{8} (1 + 2 x^{9})^{5} d x

\frac{182}{27}

Decimal Notation

6.74074 \dots

Solution steps

\int_{0}^{1} x^{8} (1 + 2 x^{9})^{5} d x

Apply u-substitution

: \int_{1}^{3} \frac{u ^{5}}{18} d u

= \int_{1}^{3} \frac{u ^{5}}{18} d u

Take the constant out:

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

= \frac{1}{18} \cdot \int_{1}^{3} u^{5} d u

Apply the Power Rule

: [\frac{u ^{6}}{6}]_{1}^{3}

= \frac{1}{18} [\frac{u ^{6}}{6}]_{1}^{3}

Compute the boundaries:

\frac{364}{3}

= \frac{1}{18} \cdot \frac{364}{3}

Simplify

= \frac{182}{27}

\int_{- \frac{π}{2}}^{π} cos (3 x) d x

\int_{- 1}^{2} - 2 y^{2} + 2 y + 4 d y

\int_{- 1}^{1} cos^{4} (x) d x

\int_{0}^{4} π (x)^{2} d x

\int_{0}^{x^{4}} e^{t} d t
