`int((1)/(5+4x^(2))+a^(3x+2))dx`

int(1)/(x^(2)+4x+5)dx

Evaluate : int(1)/(5+4x+x^(2))dx

The value of int_(3)^(5) (x^(2))/(x^(2)-4) dx, is

int(1)/(2x^(2)+5x+3)dx

Evaluate the inetgral, int(4x+1)/(sqrt(x^(2)+3x+2))dx

int(2x+1)/(x^(2)+4x-5)dx

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

int((4x+6)/(x^(2)+3x+100))dx

5. int(1)/(3x^(2)+2x+1)dx

If I_(1)=int_(0)^(1) 2^(x^(2)) dx, I_(2)=int_(0)^(1) 2^(x^(3)) dx, I_(3)=int_(1)^(2) 2^(x^(2))dx and I_(4)=int_(1)^(2) 2^(x^(3))dx then
