## Why is root 2 an irrational number?

Because √2 is not an integer (2 is not a perfect square), √2 must therefore be irrational. This proof can be generalized to show that any square root of any natural number that is not the square of a natural number is irrational.

## Is the square root of 3 a rational number?

It is denoted by √3. The square root of 3 is an irrational number. It is also known as Theodorus’ constant, named after Theodorus of Cyrene, who proved its irrationality.

## Is the square root of 15 a rational number?

15=3×5 has no square factors, so √15 cannot be simplified. It is not expressible as a rational number. It is an irrational number a little less than 4 .

## Is the square root of 64 a rational number?

Is square root of 64 a rational number? The square root of 64 is 8. 8 is a rational number.

## Is the square root of 500 a rational number?
