# Describe the following sets in Roster form:

{x R: x > x}.

Answer :

Any real number is equal to its value it is neither less nor greater.

According to the question we have to write Roster form of such real numbers which has value less than itself. As there are no such numbers.

∴ Roster form will be ϕ.

This is called as null set.
