Numbers with square roots that are whole numbers

Every 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.

Very rarely. Square roots are only whole numbers for perfect squares.

They are perfect squares.

All whole numbers between 1 and 400 (=20 square).

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".

They are the perfect squares.

Square roots of negative numbers are imaginary.

No, a square root doesn't have to be a whole number. The square root of 2.25 is 1.5. It could be said that most square roots are not whole numbers. Take just the first few integers (counting numbers). Find the square roots of the numbers 1 through 10 and you'll find three of the numbers have whole number square roots (1, 4 and 9). The other seven don't. For the numbers 11 through 20, there is only 1 number with a whole number square root (16).

They are all whole numbers (no decimal parts).

No. The square roots 8 are irrational, as are the square roots of most even numbers.

NO try and find the square root of 3. don't hurt yourself.

Yes. Not only that, they are counting numbers.

The square roots of 62 are between -7 and -8 or between 7 and 8. They are nearer to Â± 8. so, in whole numbers, that would be the answer.

Perfect square roots are square roots that have a whole number that can go into it perfectly. Nonperfect square roots are square roots that have decimal numbers going into it. Example: Perfect Square Root: 144- Square Root: 12 Nonperfect Square Root: 24- Square Root: About 4.89

4x4=16, and 5x5=25, so 4 and 5 are the whole numbers closest to the square root of 19. [And incidentally of all the square roots of all the whole numbers between 16 and 25.]

The square root of a positive whole number, N, is a number which, when multiplied by itself equals N. If N = 0 then the square root is also 0. If N is greater than 0 there will be two such numbers: one positive and the other its negative equivalent. If N is a perfect square the square roots will, themselves, be whole numbers. Otherwise, they will be irrational numbers. If N is a whole number less than 0 then there are no real square roots. Although there are square roots in the complex field, the fact that you ask this question is indicative that you are not yet ready to tackle complex numbers.

Every integer is a rational number, and some integers are perfect squares. These are the only rational numbers to have an integral square root.

The numbers 0 and 1 fall in between the two square roots of 140.

There are no two whole numbers between -0.7 and +0.7.

They are called real numbers. Negative square roots must be complex numbers.

The square roots of 71 are -8.43 and +8.43 (approx).So any whole numbers between -8 and +8 will satisfy the requirements.

No. The square roots of perfect squares are rational.
