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.
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.
No. The square roots 8 are irrational, as are the square roots of most even numbers.
They all have square roots. Square root of 1 is 1 Square root of 4 is 2 Square root of 9 is 3
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
No. Square root of 9=3. 3=3/1. Therefore not all square roots are irrational
