They are all whole numbers (no decimal parts).
No. The square roots of perfect squares are rational.
It is a perfect square.
All numbers are important.
All their roots are whole numbers.
No. Lots of square roots are not rational. Only the square roots of perfect square numbers are rational. So for example, the square root of 2 is not rational and the square root of 4 is rational.
The square root of 13 is irrational. All square roots of whole numbers are irrational unless the number is a perfect square.
The square root of a rational number is not always rational. While the square root of a perfect square (like 1, 4, or 9) is rational, the square root of non-perfect squares (like 2 or 3) is irrational. Therefore, not all square roots of rational numbers yield rational results; only those of perfect squares do.
Yes. Not only that, they are counting numbers.
All numbers have square roots. You may have meant which factors of 40 are perfect squares. That's 1 and 4.
They all have square roots. Square root of 1 is 1 Square root of 4 is 2 Square root of 9 is 3
No. The square roots 8 are irrational, as are the square roots of most even numbers.
All prime numbers have irrational number square roots, so if you try to find the square root of a non-perfect square number use them to simplify it. For example, ±√125 = ±√25*5 = ±5√5 (when you want to show both the square roots) √72 = √36*2 = 6√2 √-27 = √-9*3 = 3i√3
