Are the square roots of all positive integers irrational ?If not,give an example of the square root of a number that is a rational number.

${\underline{\boxed{ \purple{ \maltese \: {\textsf{\textbf{\purple{Answer}}}}}}}}$

If numbers such as $\sf{ \sqrt{4} = 2, \: \sqrt{9} = 3}$ are considered,

Then here,2 and 3 are rational numbers.Thus,the square roots of all positive integers are not rational.
