integrate(x^6/(b*x^2+a)^(1/6),x, algorithm="giac")
 

Output:

integrate(x^6/(b*x^2 + a)^(1/6), x)
 

Mupad [F(-1)]

Timed out. \[ \int \frac {x^6}{\sqrt [6]{a+b x^2}} \, dx=\int \frac {x^6}{{\left (b\,x^2+a\right )}^{1/6}} \,d x \] Input:

int(x^6/(a + b*x^2)^(1/6),x)
 

Output:

int(x^6/(a + b*x^2)^(1/6), x)
 

Reduce [F]

\[ \int \frac {x^6}{\sqrt [6]{a+b x^2}} \, dx=\int \frac {x^{6}}{\left (b \,x^{2}+a \right )^{\frac {1}{6}}}d x \] Input:

int(x^6/(b*x^2+a)^(1/6),x)
 

Output:

int(x**6/(a + b*x**2)**(1/6),x)
