Numbers with square roots that are whole numbers

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

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.

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.

Every whole number

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

Just check the squares of a few whole numbers. If 55 is between two of those squares, then its square root is also between the corresponding square roots.

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.]

There are many pairs of consecutive whole numbers that lie between the square roots of 46, which are approx -6.78 and +6.78. -4 and -3, for example.

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

I suspect you are really asking for between which two whole numbers does the square root of 150 lie. The square root of 150 lies between 12 and 13 (mathematically: 12 < √150 < 13).

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".

The square roots of 71 are -8.43 and +8.43 (approx).So any whole numbers between -8 and +8 will satisfy the requirements. One answer: -2 and -1.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, 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).

To figure this out, I always start with square roots I know, and that are close to 47. So, first, I would figure out that the square root of a number such as 36 is 6. The square root of 49 is 7. Now, since there are no other whole numbers between 6 and 7, and the square root of 47 falls between the square root of 36 and 49, we can say that the square root of 47 is between the whole numbers 6 and 7.

They are perfect squares.

No, there aren't any square numbers between 70 and 80. From 70 to 80, no number has a perfect square root, so no square number exists between 70 to 80.

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

They are the perfect squares.

They are called perfect squares.

Square roots of negative numbers are imaginary.

The square roots of 82 are -9.055 and 9.055. So two consecutive whole numbers that lie between the square roots of 82 are any consecutive numbers from the set {-9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

twenty three has no square root but it will be in between 4 squared and 5 squared but more towards the 5. also there is + and - square roots such as the two square roots of 9 are +3 and -3. - times - = + and + times + = +.

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.
