int(dx)/((x^(4)-1)^(2))

int(x^(9)dx)/((x^(4)-1)^(2))

int(dx)/(x^(4)+x^(2)+1)

int(dx)/((4x^(2)-1))=?

Evaluate int(dx)/(x^(4)(x^(3)+1)^(2))

int(dx)/((1-2^(x))^(4))dx

If int(dx)/((x-1)^((3)/(4))(x+2)^((5)/(4)))=k((x-1)/(x+2))^((1)/(4))+c , then the number of divisors of 30k is

"int(dx)/(sqrt((x+1)^(2)+4))

int(dx)/(sqrt((x+1)^(2)+4))

" (b) "int(dx)/(sqrt(4x^(2)-1))
