Evaluate : int_(1)^(2)(x^(3)-1)/(x^(2))dx

int_(1)^(2)(3x)/(9x^(2)-1)dx

Evaluate int_(1)^(2)((x+1)^(3))/(x^(2))dx

int_(-1)^(-2)x^(3)(1-x^(2))dx=?

Evaluate int_(1)^(2) ((x+1)^(3))/(x^(2)) dx

int_(2)^(3) (2x)/(1+x^(2))dx

int_(-1)^(2)|x^(3)-x|dx

" 2."int_(0)^(1)(x^2)/(1+x^(3))dx

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

Let I_(1)=int_(0)^(1)(5^(x))/(x+1)dx and I_(2)=int_(0)^(1)(x^(2))/(5^(x^(3))(2-x^(3)))dx then (I_(1))/(I_(2))=
