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

Solution

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

Solution

\frac{553}{3}

+1

Decimal Notation

184.33333 \dots

Solution steps

\int_{1}^{8} x^{2} + 2 d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{1}^{8} x^{2} d x + \int_{1}^{8} 2 d x

\int_{1}^{8} x^{2} d x = \frac{511}{3}

\int_{1}^{8} 2 d x = 14

= \frac{511}{3} + 14

Simplify

\frac{511}{3} + 14 : \frac{553}{3}

= \frac{553}{3}
