Rational numbers, integers, whole numbers, natural numbers.

Work Step by Step

First, let us simplify the radical: $\sqrt {100}$=$10$ because $10^2=100$. A natural number is a number in the set $\{1,2,3,…….\}$. The number $10$ is contained in this set and is therefore a natural number. Since the set of natural numbers is contained in the sets of whole numbers, integers, and rational numbers, the number $\sqrt {100}$ is also contained within all of these sets.
