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

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

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

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

= - \frac{5 ( - 1 ) ^{\frac{4}{5}}}{2 \cdot 2 ^{\frac{1}{5}}} + \frac{5}{4}

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

= - \frac{5}{2 \cdot 2 ^{\frac{1}{5}}} + \frac{5}{4}
