integral from 0 to 2 of xsqrt(4+x^2)

\int_{0}^{2} x 4 + x^{2} d x

\frac{16 2 - 8}{3}

Decimal

4.87580 \dots

Solution steps

\int_{0}^{2} x 4 + x^{2} d x

Apply u-substitution

= \int_{2}^{22} u^{2} d u

Apply the Power Rule

= [\frac{u ^{3}}{3}]_{2}^{22}

Compute the boundaries:

\frac{16 2}{3} - \frac{8}{3}

= \frac{16 2}{3} - \frac{8}{3}

Simplify

= \frac{16 2 - 8}{3}
