integral from 1 to 3 of (3/(x^2))

\int_{1}^{3} (\frac{3}{x ^{2}}) d x

2

Solution steps

\int_{1}^{3} \frac{3}{x ^{2}} d x

Take the constant out:

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

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

Apply the Power Rule

= 3 [- \frac{1}{x}]_{1}^{3}

Compute the boundaries:

\frac{2}{3}

= 3 \cdot \frac{2}{3}

Simplify

= 2
