`int_(1)^(9)(x^((3)/(2))+2x+3)dx`

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

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

int_(0)^(3)(x^(2)+1)dx

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

int3x^(1//2)(1+x^(3//2))dx

The value of int_(0)^(1) (1)/(2x-3)dx is

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

(9) int(4-5x)(3-x)^(-(3)/(2))dx

int_(1)^(3) (dx)/(x^(2)(x+1))=(2)/(3)+log .(2)/(3)

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