integral from 2 to 3 of 4/(x^3)

\int_{2}^{3} \frac{4}{x ^{3}} d x

\frac{5}{18}

Decimal Notation

0.27777 \dots

Solution steps

\int_{2}^{3} \frac{4}{x ^{3}} d x

Take the constant out:

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

= 4 \cdot \int_{2}^{3} \frac{1}{x ^{3}} d x

Apply the Power Rule

: [- \frac{1}{2 x ^{2}}]_{2}^{3}

= 4 [- \frac{1}{2 x ^{2}}]_{2}^{3}

Compute the boundaries:

\frac{5}{72}

= 4 \cdot \frac{5}{72}

Simplify

= \frac{5}{18}

\int_{0}^{3} (e^{\frac{x}{3}} - 3) d x

\int_{0}^{1} (8 ln (x)) d x

\int_{0}^{\frac{π}{2}} cos (3 t) d t

\int_{0}^{\frac{π}{4}} x^{2} + 1 d x

\int_{t}^{\frac{t}{n}} De (a (t)^{b}) d t
