integral from-27 to 8 of 1/(x^{1/3)}

\int_{- 27}^{8} \frac{1}{x ^{\frac{1}{3}}} d x

- \frac{15}{2}

Decimal

- 7.5

Solution steps

\int_{- 27}^{8} \frac{1}{x ^{\frac{1}{3}}} d x

Find undefined (singularity) points:

x = 0

If exist

b, a < b < c, f (b) =

undefined

, \int_{a}^{c} f (x) d x = \int_{a}^{b} f (x) d x + \int_{b}^{c} f (x) d x

= \int_{- 27}^{0} \frac{1}{x ^{\frac{1}{3}}} d x + \int_{0}^{8} \frac{1}{x ^{\frac{1}{3}}} d x

\int_{- 27}^{0} \frac{1}{x ^{\frac{1}{3}}} d x = - \frac{27 ( - 1 ) ^{\frac{2}{3}}}{2}

\int_{0}^{8} \frac{1}{x ^{\frac{1}{3}}} d x = 6

= - \frac{27 ( - 1 ) ^{\frac{2}{3}}}{2} + 6

Simplify

- \frac{27 ( - 1 ) ^{\frac{2}{3}}}{2} + 6 : - \frac{15}{2}

= - \frac{15}{2}
