What makes a square root rational?

The square roots of 9, for instance are 3 and -3, which are integers, and integers are rational. You can also take the square root of a rational non-integer, that is a fraction, and if the numerator and denominator are both perfect squares, you will have rational square roots.

Is the cube root of negative 27 an irrational number?

R D Sharma – Mathematics 9 so it is a rational number.

Is the square root of 27 a rational number?

No, so the root 27 is not a rational number. So if you can prove that is irrational you have also proved that is irrational. There are plenty of proofs on the internet that is irrational e.g.: Prove that the square root of 3 is irrational So the answer to your question is that is not rational.

Can you prove that the square root of any irrational number?

Prove that the square root of any irrational number is irrational. => Suppose not. The square root of any irrational number is rational. => Let m be some irrational number. It follows that m is rational.

Is the square root of an integer always rational?

If the square root of an integer is itself an integer, then by definition it is rational – If the square root is not integer, then it must be irrational. Put another way the only integers for which the square root of an integer can be rational is if is a perfect square – that is where x is an integer.

Is a perfect square a rational number?

In other words, square roots of perfect squares are integers and, therefore, rational, while square roots of other numbers are neither. (The reason is that means , and every prime number appears an even number of times in , so it must do so in , so it must do so in , so is a perfect square). is a perfect square, so , a rational number.
