## Solution

Square root of positive integers is not always irrational. For example:  $$4$$ and $$9$$ are  integers whose square roots are rational numbers.
As,$$\sqrt{4}=2$$ and$$\sqrt{9}=3$$
Here, $$2$$ and $$3$$ are rational numbers.
Therefore, the square root of every positive integer is not always an irrational number.
