Yes. In fact, they are integers.
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.
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.
Yes.
They are perfect squares.
Yes. In fact, they are integers.
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.
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.

-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.
Yes
