integral from 1 to 3 of 7/(x^2)

\int_{1}^{3} \frac{7}{x ^{2}} d x

\frac{14}{3}

Decimal

4.66666 \dots

Solution steps

\int_{1}^{3} \frac{7}{x ^{2}} d x

Take the constant out:

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

= 7 \cdot \int_{1}^{3} \frac{1}{x ^{2}} d x

Apply the Power Rule

= 7 [- \frac{1}{x}]_{1}^{3}

Compute the boundaries:

\frac{2}{3}

= 7 \cdot \frac{2}{3}

Simplify

= \frac{14}{3}
