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

= \int_{0}^{3} \frac{1}{( 6 - 2 x ) ^{\frac{1}{3}}} d x + \int_{3}^{5} \frac{1}{( 6 - 2 x ) ^{\frac{1}{3}}} d x

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

\int_{3}^{5} \frac{1}{( 6 - 2 x ) ^{\frac{1}{3}}} d x = - \frac{3 ( - 1 ) ^{\frac{2}{3}}}{2 ^{\frac{2}{3}}}

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

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

= \frac{3 \cdot 3 ^{\frac{2}{3}}}{2 \cdot 2 ^{\frac{1}{3}}} - \frac{3}{2 ^{\frac{2}{3}}}
