Timed out. \[ \int (c x)^{5/2} \sqrt [4]{a-b x^2} \, dx=\int {\left (c\,x\right )}^{5/2}\,{\left (a-b\,x^2\right )}^{1/4} \,d x \] Input:

int((c*x)^(5/2)*(a - b*x^2)^(1/4),x)
 

Output:

int((c*x)^(5/2)*(a - b*x^2)^(1/4), x)
 

Reduce [F]

\[ \int (c x)^{5/2} \sqrt [4]{a-b x^2} \, dx=\frac {\sqrt {c}\, c^{2} \left (-2 \sqrt {x}\, \left (-b \,x^{2}+a \right )^{\frac {1}{4}} a x +8 \sqrt {x}\, \left (-b \,x^{2}+a \right )^{\frac {1}{4}} b \,x^{3}+3 \left (\int \frac {\sqrt {x}}{\left (-b \,x^{2}+a \right )^{\frac {3}{4}}}d x \right ) a^{2}\right )}{32 b} \] Input:

int((c*x)^(5/2)*(-b*x^2+a)^(1/4),x)
 

Output:
