(10*x**(5/6)*sqrt(x**(2/3)*a + b)*a**2*x + 154*sqrt(x)*sqrt(x**(2/3)*a + b )*b**2 - 22*x**(1/6)*sqrt(x**(2/3)*a + b)*a*b*x - 77*x**(2/3)*int((x**(1/6 )*sqrt(x**(2/3)*a + b))/(x**(2/3)*b**2 + 2*x**(1/3)*a*b*x + a**2*x**2),x)* a*b**3 - 77*int((x**(1/6)*sqrt(x**(2/3)*a + b))/(x**(2/3)*b**2 + 2*x**(1/3 )*a*b*x + a**2*x**2),x)*b**4)/(15*a**3*(x**(2/3)*a + b))
