They are perfect squares.
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.
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.
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. Square roots of whole numbers that don't result in whole numbers (e.g. the square root of 64 is 8), are considered to be "irrational numbers".
No. Square roots of whole numbers that don't result in whole numbers (e.g. the square root of 64 is 8), are considered to be "Irrational Numbers".
Yes. Not only that, they are counting numbers.
The square root of 13 is irrational. All square roots of whole numbers are irrational unless the number is a perfect square.
Numbers with square roots that are whole numbers
Every whole number
A rational number is a number that can be expressed as the division of two integers, while the divisor is not zero. An irrational number is any number that is not rational.Whole numbers are rational, because the divisor is 1. It has nothing to do with square roots.
It can be. The square roots of 2.25 are -1.5 and 1.5: rational numbers.
Very rarely. Square roots are only whole numbers for perfect squares.
