Is the square root of 24 rational or irrational?

The square root of 24 is irrational. This is because it can be simplified to ( \sqrt{4 \times 6} = 2\sqrt{6} ), and since ( \sqrt{6} ) is not a perfect square and cannot be expressed as a fraction, ( \sqrt{24} ) cannot be expressed as a ratio of two integers. Therefore, it is classified as an irrational number.
