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, 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.
The square root of 13 is irrational. All square roots of whole numbers are irrational unless the number is a perfect square.
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.
No. Square root of 9=3. 3=3/1. Therefore not all square roots are irrational
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
