integral from 5 to 100 of 2x^{-3}

\int_{5}^{100} 2 x^{- 3} d x

\frac{399}{10000}

Decimal Notation

0.0399

Solution steps

\int_{5}^{100} 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_{5}^{100} x^{- 3} d x

Apply the Power Rule

: [- \frac{1}{2 x ^{2}}]_{5}^{100}

= 2 [- \frac{1}{2 x ^{2}}]_{5}^{100}

Compute the boundaries:

\frac{399}{20000}

= 2 \cdot \frac{399}{20000}

Simplify

= \frac{399}{10000}

\int_{1}^{2} e^{- x} \cdot ln (x) d x

\int_{0}^{\frac{π}{2}} x cos (5 x) d x

\int_{0}^{4} \frac{4 - x}{( x + 2 ) ^{2}} d x

\int_{0}^{2} 44 z^{2} ln (z) d z

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