The square root of 30, denoted as √30, is an irrational number because it cannot be expressed as a fraction of two integers. Its decimal expansion is approximately 5.477, which goes on forever without repeating. The rationale behind its classification as irrational lies in the fact that 30 is not a perfect square, meaning there is no integer that, when multiplied by itself, equals 30. Thus, √30 is often left in its radical form for exactness in mathematical expressions.
