integral from 0 to 4 of 2/(sqrt(x))

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

8

Solution steps

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

Take the constant out:

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

= 2 \cdot \int_{0}^{4} \frac{1}{x} d x

Apply the Power Rule

= 2 [2 x^{\frac{1}{2}}]_{0}^{4}

Apply radical rule:

= 2 [2 x]_{0}^{4}

Compute the boundaries:

4

= 2 \cdot 4

Simplify

= 8
