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

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

\int_{- 8}^{0} \frac{1}{x ^{\frac{1}{3}}} d x = - 6 (- 1)^{\frac{2}{3}}

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

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