integral from 1 to 8 of sqrt(1+3m)

\int_{1}^{8} 1 + 3 m d m

26

Solution steps

\int_{1}^{8} 1 + 3 m d m

Apply u-substitution

= \int_{4}^{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_{4}^{25} u d u

Apply the Power Rule

= \frac{1}{3} [\frac{2}{3} u^{\frac{3}{2}}]_{4}^{25}

Compute the boundaries:

78

= \frac{1}{3} \cdot 78

Simplify

= 26
