Reduce [N/A]

Not integrable

Time = 0.21 (sec) , antiderivative size = 50, normalized size of antiderivative = 0.64 \[ \int \frac {\sqrt [4]{-1+x^4} \left (-1+x^8\right )}{x^6 \left (1+x^8\right )} \, dx=\frac {\left (x^{4}-1\right )^{\frac {1}{4}} x^{4}-\left (x^{4}-1\right )^{\frac {1}{4}}-10 \left (\int \frac {\left (x^{4}-1\right )^{\frac {1}{4}}}{x^{14}+x^{6}}d x \right ) x^{5}}{5 x^{5}} \] Input:

int((x^4-1)^(1/4)*(x^8-1)/x^6/(x^8+1),x)
 

Output:
