If the square root is a whole number, then the square of the square root, the original number, is also a whole number; all whole numbers can be expressed as themselves over 1, and so are rational numbers.
The answer is thus any square number, ie the square of the natural numbers: 1 (1²), 4 (2²), 9 (3²), 16 (4²), etc.
It is another rational number whose numerator and denominator (in the ratio's simplest form) are perfect squares.
A non-square rational number is a rational number that cannot be expressed as the square of any rational number. For example, ( \frac{2}{3} ) is a non-square rational number because there are no rational numbers whose square equals ( \frac{2}{3} ). In general, any rational number that does not have a perfect square as its numerator and denominator is considered a non-square rational.
-27 is one possible answer.
27 is a perfect cube.
That's a perfect cube.
A perfect square.
How about 27 whose cube root is 3 which is a rational whole number.
Rational numbers whose square roots are whole numbers are themselves whole numbers. They are called square numbers, e.g. 1, 4, 9, 16, 25 and so on.

Square root of a rational number may either be rational or irrational. For example 1/4 is a rational number whose square root is 1/2. Similarly, 4 is 4/1 which is rational and the square root is 2 which of course is also rational. However, 1/2 and 2 are rational, but their square roots are irrational. We can say the square root of a rational number is always a real number. We can also say the rational numbers whose square roots are also rational are perfect squares or fractions involving perfect squares.
