Set of complex numbers can be represented as C= x+i y: x ∈ R, y ∈ R, i=√-1 C= x+i y: x, y ∈ R text and i=√-1

Q. Which of the following represent correct form of set of complex numbers?

$C = {x + i y : x \in R, y \in R, i = - 1}$

$C = {x + i y : x \in R, y \in /}$

$C = {x + i y : x \in l, y \in l}$

All of the above

Set of complex numbers can be represented as
$C = {x + i y : x \in R, y \in R, i = - 1}$
$C = {x + i y : x, y \in R and i = - 1}$

Q. Which of the following represent correct form of set of complex numbers?

C={x+iy:x∈R,y∈R,i=−1​}

C={x+iy:x∈R,y∈/}

C={x+iy:x∈l,y∈l}

All of the above

Set of complex numbers can be represented as C={x+iy:x∈R,y∈R,i=−1​} C={x+iy:x,y∈R and i=−1​}

$C = {x + i y : x \in R, y \in R, i = - 1}$

$C = {x + i y : x \in R, y \in /}$

$C = {x + i y : x \in l, y \in l}$

Set of complex numbers can be represented as
$C = {x + i y : x \in R, y \in R, i = - 1}$
$C = {x + i y : x, y \in R and i = - 1}$
