Which statement gives the correct comparative estimate of the spiral distance \( \sqrt{32} \)?

Answer and explanation

Correct answer: It is between \(5\) and \(6\)

Since \(5^2=25\) and \(6^2=36\), and \(25<32<36\), we get \(5<\sqrt{32}<6\). Therefore, the spiral distance \(\sqrt{32}\) lies between \(5\) and \(6\). The option between \(4\) and \(5\) is incorrect because \(\sqrt{32}>\sqrt{25}=5\). Exam tip: estimate a square root by locating the nearest perfect squares on either side of the number.
