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

= \int_{0}^{4} (x - 4)^{- \frac{2}{3}} d x + \int_{4}^{6} (x - 4)^{- \frac{2}{3}} d x

\int_{0}^{4} (x - 4)^{- \frac{2}{3}} d x = - 3 (- 1)^{\frac{1}{3}} \cdot 4^{\frac{1}{3}}

\int_{4}^{6} (x - 4)^{- \frac{2}{3}} d x = 3 \cdot 2^{\frac{1}{3}}

= - 3 (- 1)^{\frac{1}{3}} \cdot 4^{\frac{1}{3}} + 3 \cdot 2^{\frac{1}{3}}

- 3 (- 1)^{\frac{1}{3}} \cdot 4^{\frac{1}{3}} + 3 \cdot 2^{\frac{1}{3}} : 3 \cdot 4^{\frac{1}{3}} + 3 \cdot 2^{\frac{1}{3}}

= 3 \cdot 4^{\frac{1}{3}} + 3 \cdot 2^{\frac{1}{3}}
