वर्गमूल सर्पिल में \(\sqrt{168}\) और \(\sqrt{170}\) की सही तुलना कौन-सी है?
Which is the correct comparison of \(\sqrt{168}\) and \(\sqrt{170}\) in a square root spiral?
Explanation opens after your attempt
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)
Concept
Since \(168<169=13^2\), \(\sqrt{168}<13\). Since (170>169), \(\sqrt{170}>13\).
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), \(\sqrt{170}>13\).
Exam Tip
\(168<169=13^2\), इसलिए \(\sqrt{168}<13\)। (170>169), इसलिए \(\sqrt{170}>13\)।
