`int_(1)^(2)2x^(2)`dx

IfI_(1)=int_(0)^(1)2^(x^(2)),I_(2)=int_(0)^(1)2^(x^(3))dx,I_(3)=int_(1)^(2)2^(x^(2))dx,I_(4)=int_(1)^(2)2^(x^(3))dx then which of the following is/are true? I_(1)>I_(2)(b)I_(2)>I_(1)I_(3)>I_(4)(d)I_(3)

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^(2))dx then

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

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

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

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

int_(1)^(2)([x^(2)]-[x]^(2))dx where [.] ldenotes the greatest integer function is equal to

int_(1)^(2)(x^(x^(2))+[x^(2)]^(x))dx

int_(1)^(2)(1)/(x^(2)-2x+2)dx =
