integral from 0 to 3 of sqrt(3x+16)

\int_{0}^{3} 3 x + 16 d x

\frac{122}{9}

Decimal

13.55555 \dots

Solution steps

\int_{0}^{3} 3 x + 16 d x

Apply u-substitution

= \int_{16}^{25} \frac{u}{3} d u

Take the constant out:

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

= \frac{1}{3} \cdot \int_{16}^{25} u d u

Apply the Power Rule

= \frac{1}{3} [\frac{2}{3} u^{\frac{3}{2}}]_{16}^{25}

Compute the boundaries:

\frac{122}{3}

= \frac{1}{3} \cdot \frac{122}{3}

Simplify

= \frac{122}{9}
