integral from 8 to 12 of 2/(x^3)

\int_{8}^{12} \frac{2}{x ^{3}} d x

\frac{5}{576}

Decimal

0.00868 \dots

Solution steps

\int_{8}^{12} \frac{2}{x ^{3}} d x

Take the constant out:

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

= 2 \cdot \int_{8}^{12} \frac{1}{x ^{3}} d x

Apply the Power Rule

= 2 [- \frac{1}{2 x ^{2}}]_{8}^{12}

Compute the boundaries:

\frac{5}{1152}

= 2 \cdot \frac{5}{1152}

Simplify

= \frac{5}{576}
