Question

Is the square root of 255 rational or irrational

Answer 1

The square root of 255 is considered an irrational number. A number is classified as irrational if it cannot be expressed as a fraction of two integers. Since 255 is not a perfect square (it does not have an integer value whose square equals 255), \(\sqrt{255}\) cannot be simplified to a fraction of two integers. Therefore, \(\sqrt{255}\) is irrational.
