Natural numbers is the set of counting numbers i.e. 1, 2, 3,…

So $\sqrt{80}$ is not present in this set.

Whole numbers is the set of natural numbers along with 0 i.e. 0, 1, 2,…

So $\sqrt{80}$ is not present in this set.

Integers are set of whole numbers along with negative numbers i.e. …,-2, -1, 0, 1, 2,…

So $\sqrt{80}$ is not present in this set.

Rational numbers are set of numbers that can be expressed in the form $\frac{p}{q}.$

So $\sqrt{80}$ is not present in this set.

Irrational numbers are set of numbers that cannot be expressed in the form $\frac{p}{q}.$

Hence $\sqrt{80}$ is present in this set.

Real numbers are set of rational and irrational numbers together.

Hence $\sqrt{80}$ is present in this set.

Answer: Irrational number and Real number.
