Let `I_1=int_0^1 (dx)/(1+x^(1/3))` and `I_2=int_0^1 (dx)/(1+x^(1/4))` then `4I_1+3I_2=`

If I=int_(0)^(1) (dx)/(1+x^(4)) , then

If l_(1)=int_(0)^(1)(dx)/(sqrt(1+x^(2))) and I_(2)=int_(0)^(1)(dx)/(|x|) then

Let I_1=int_0^1 e^x/(1+x)dx and I_2=int_0^1(x^2e^(x^2))/(2-x^3)dx Statement-1: I_1/I_2=3e Statement-2: int_a^b f(x)dx=int_a^b f(a+b-x)dx (A) Both 1 and 2 are true and 2 is the correct explanation of 1 (B) Both 1 and 2 are true and 2 is not correct explanation of 1 (C) 1 is true but 2 is false (D) 1 is false but 2 is true

If I=int_(0)^(1) (1)/(1+x^(pi//2))dx then

int_(0)^(1)(dx)/(sqrt(1+x^(4)))=I, then

Let I_1=int_0^1e^(x^2)dx and I_2=int_0^(12)2^(x^2)e^(x^2)dx then the value of I_1 +I_2 is equal to
