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.
-27 is one possible answer.
27 is a perfect cube.
That's a perfect cube.
It is a real rational negative integer number whose value is -3
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.
They are perfect squares.

A perfect square.
It's rational. It can be written as the quotient of two numbers whose HCF is one.

They are all non-positive rational numbers.
