A rational number can be written as a fraction a/b of two integers a and b. Since SQRT(4) = 2 (an integer) and SQRT (9) = 3 (also an integer), then SQRT (4/9) is rational.

It's rational: √4 = 2 and √9 = 3, so √(4/9) = 2/3,
which is a fraction. So it's rational.

√ [4/9] = √4 / √9 = 2 / 3
A rational number is a number that can be put in the form p / q where p and q are integers.
In this case 2 and 3 are integers thus √[4/9] is rational.

Rational because the answer would be 2/3- and the numbers in that fraction are rational integers.
