Question

Question: List all the subsets of the real number system in which v2 belongs.

Answer 1

You have the following number:

√2

The previous number is a number with infinite non-periodic decimals. In fact, you have:

√2 = 1.414213562...

This kind of real number is known as an irrational number, and it is the only subset from the real numbers √2 belongs to.
