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

= \int_{- 1}^{0} \frac{1}{x ^{\frac{1}{5}}} d x + \int_{0}^{32} \frac{1}{x ^{\frac{1}{5}}} d x

\int_{- 1}^{0} \frac{1}{x ^{\frac{1}{5}}} d x = - \frac{5 ( - 1 ) ^{\frac{4}{5}}}{4}

\int_{0}^{32} \frac{1}{x ^{\frac{1}{5}}} d x = 20

= - \frac{5 ( - 1 ) ^{\frac{4}{5}}}{4} + 20
