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

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

\int_{1}^{2} \frac{1}{( x - 2 ) ^{\frac{1}{5}}} d x = - \frac{5 ( - 1 ) ^{\frac{4}{5}}}{4}

\int_{2}^{5} \frac{1}{( x - 2 ) ^{\frac{1}{5}}} d x = \frac{5 \cdot 3 ^{\frac{4}{5}}}{4}

= - \frac{5 ( - 1 ) ^{\frac{4}{5}}}{4} + \frac{5 \cdot 3 ^{\frac{4}{5}}}{4}

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

= - \frac{5}{4} + \frac{5 \cdot 3 ^{\frac{4}{5}}}{4}
