Which option is correct about \(\sqrt{100}\) and \(\sqrt{101}\) in a square root spiral?

Answer and explanation

Correct answer: \(\sqrt{100}=10\) and \(\sqrt{101}\) lies between \(10\) and \(11\)

Since \(100=10^2\), \(\sqrt{100}=10\). Also, \(10^2=100<101<121=11^2\), so \(\sqrt{101}\) lies between \(10\) and \(11\) and is not a whole number. Option C may seem close, but \(\sqrt{101}=11\) would require \(101=121\). Exam tip: To locate a square root, compare the number with nearby perfect squares.
