integral from 1 to n of 1/(x^p)

\int_{1}^{n} \frac{1}{x ^{p}} d x

\frac{n ^{- p + 1} - 1}{- p + 1}

Solution steps

\int_{1}^{n} \frac{1}{x ^{p}} d x

Apply the Power Rule

: [\frac{x ^{- p + 1}}{- p + 1}]_{1}^{n}

= [\frac{x ^{- p + 1}}{- p + 1}]_{1}^{n}

Compute the boundaries:

\frac{n ^{- p + 1}}{- p + 1} - \frac{1}{- p + 1}

= \frac{n ^{- p + 1}}{- p + 1} - \frac{1}{- p + 1}

Simplify

= \frac{n ^{- p + 1} - 1}{- p + 1}

\int_{0}^{1} \frac{40}{x ^{2} - 25} d x

\int_{1}^{2} 2 x^{3} + 2 x^{- 2} d x

\int_{3}^{7} x e^{- 2 x} d x

\int_{1}^{\frac{3}{2}} 3 y - 2 y^{2} d y

\int_{5}^{8} \frac{30}{x} d x
