Correct Answer

A. \(\sqrt{168}\) (12) और (13) के बीच, \(\sqrt{170}\) (13) और (14) के बीच है\(\sqrt{168}\) lies between (12) and (13), \(\sqrt{170}\) lies between (13) and (14)

Step 1

Concept

Since \(168<169=13^2\), \(\sqrt{168}<13\). Since (170>169), \(\sqrt{170}>13\).

Step 2

Why this answer is correct

The correct answer is A. \(\sqrt{168}\) (12) और (13) के बीच, \(\sqrt{170}\) (13) और (14) के बीच है / \(\sqrt{168}\) lies between (12) and (13), \(\sqrt{170}\) lies between (13) and (14). Since \(168<169=13^2\), \(\sqrt{168}<13\). Since (170>169), \(\sqrt{170}>13\).

Step 3

Exam Tip

\(168<169=13^2\), इसलिए \(\sqrt{168}<13\)। (170>169), इसलिए \(\sqrt{170}>13\)।
