Answer 2

Answer:

A = {x : x equal not x} represent null set or empty set.

Step-by-step explanation:

If the no of elements in a set is 0, then that set is known as an empty set or null set. It is denoted by { } or ∅.

The given set is

A = {x : x equal not x}

For all value of x the statement x=x is true by reflexive property.

We need to find the value of x for which x≠x, that is not true for any value of x.

The number of elements is set A is 0.

Since the size of set A is 0, therefore the set A = {x : x equal not x} represent null set or empty set.
