tafzijdeq
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.
