If \(n\) is a positive integer that is not a perfect square, which statement about \(\sqrt{n}\) is correct?

Answer and explanation

Correct answer: It is an irrational number and can be represented on the number line using a geometric construction.

When \(n\) is not a perfect square, \(\sqrt{n}\) is irrational. Its length can be obtained through a semicircle construction and marked from 0 on the number line. Exam tip: irrational does not mean unrepresentable.
