`int(3dx)/((x+4)(x+6))=?`

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

int(dx)/((x+1)^((6)/(5))(x-3)^((4)/(5)))=

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

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

int(4x^3+3x)/(x^4+1)dx=?

int(3x+1/x+4)dx=

int(1)/(x^(4)+x^(6))*dx

int (3x^2 - 4)x dx

int(6x+4)/((x-2)(x-3))dx is equal to

Evaluate : (i) int(3x^(2))/((1+x^(6)))dx (ii) int(x^(3))/((x^(2)+1)^(3))dx (iii) (x^(8))/((1-x^(3))^(1//3))dx
