\[ \int x^4 \left (a+b x^2\right )^{5/6} \, dx=\int { {\left (b x^{2} + a\right )}^{\frac {5}{6}} x^{4} \,d x } \] Input:

integrate(x^4*(b*x^2+a)^(5/6),x, algorithm="giac")
 

Output:

integrate((b*x^2 + a)^(5/6)*x^4, x)
 

Mupad [F(-1)]

Timed out. \[ \int x^4 \left (a+b x^2\right )^{5/6} \, dx=\int x^4\,{\left (b\,x^2+a\right )}^{5/6} \,d x \] Input:

int(x^4*(a + b*x^2)^(5/6),x)
 

Output:

int(x^4*(a + b*x^2)^(5/6), x)
 

Reduce [F]

\[ \int x^4 \left (a+b x^2\right )^{5/6} \, dx=\int \left (b \,x^{2}+a \right )^{\frac {5}{6}} x^{4}d x \] Input:

int(x^4*(b*x^2+a)^(5/6),x)
 

Output:

int((a + b*x**2)**(5/6)*x**4,x)
