integral from 3 to 5 of x/8

\int_{3}^{5} \frac{x}{8} d x

1

Solution steps

\int_{3}^{5} \frac{x}{8} d x

Take the constant out:

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

= \frac{1}{8} \cdot \int_{3}^{5} x d x

Apply the Power Rule

= \frac{1}{8} [\frac{x ^{2}}{2}]_{3}^{5}

Compute the boundaries:

8

= \frac{1}{8} \cdot 8

Simplify

= 1
