    Take a calculator and do each square root. The one that does not go on forever is rational.

    irrational numbers can't be expressed as fractions.

    also if you have a square root left over after simplifying.. it's irrational..

    yeah and since 9 can be expressed as a fraction which is 9/1 it's rational. irrational numbers is when you have square roots remaining, a pi, or e.

    In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, p and q, with the denominator q not equal to zero. Since q may be equal to 1, every integer is a rational number. so in that case when we got the square root of 81 is 9 let p = 9 and q = 1 9/1
