Yes, they are.
Yes. In fact, they are integers.
Perfect squares will never be irrational numbers. A perfect square is the result of multiplying an integer by itself, which always yields a rational number. Since the square root of a perfect square is an integer, perfect squares are always rational. Thus, they cannot be irrational.
Every integer is a rational number, and some integers are perfect squares. These are the only rational numbers to have an integral square root.
No. The square roots of perfect squares are rational.
Yes. Not only that, they are counting numbers.

No. The square roots of perfect squares are rational.
That isn't possible. Rational numbers either terminate or have a repeating pattern, and irrational numbers are all the rest. Perfect squares terminate, therefore they are rational.
Yes. Not only that, they are counting numbers.
No, not all square roots are rational numbers. A rational number is a number that can be expressed as a fraction where the numerator and denominator are integers and the denominator is not zero. Square roots that are perfect squares, such as √4 or √9, are rational numbers because they can be expressed as whole numbers. However, square roots of non-perfect squares, such as √2 or √3, are irrational numbers because they cannot be expressed as a simple fraction.
yes it can All perfect squares are rational numbers as the definition of a perfect square is a number which is the product of an integer with itself. An integer is a rational number, and multiplying an integer by an integer produces another integer.
-90 squared is rational - it is +8100. All perfect squares are not only rational but they are integers.
It is a rational number - as are ALL perfect squares.
