sqroot(2), sqroot(3) and sqroot(5)
is irrational numbers.
sqroot(30) is irrational too.

The real numbers are the numbers that can be written in decimal notation, including those that require an infinite decimal expansion. The set of real numbers includes all integers, positive and negative; all fractions; and the irrational numbers, those whose decimal expansions never repeat.
