\[ \int \frac {x^7}{\left (8 c-d x^3\right )^2 \sqrt {c+d x^3}} \, dx=\int \frac {\sqrt {d \,x^{3}+c}\, x^{7}}{d^{3} x^{9}-15 c \,d^{2} x^{6}+48 c^{2} d \,x^{3}+64 c^{3}}d x \] Input:
int(x^7/(-d*x^3+8*c)^2/(d*x^3+c)^(1/2),x)
Output:
int((sqrt(c + d*x**3)*x**7)/(64*c**3 + 48*c**2*d*x**3 - 15*c*d**2*x**6 + d **3*x**9),x)
