वर्गमूल सर्पिल में \(\sqrt{255}\) और \(\sqrt{257}\) की संख्या-रेखा स्थिति के बारे में सही कथन कौन-सा है?
Which statement about the number-line positions of \(\sqrt{255}\) and \(\sqrt{257}\) in a square root spiral is correct?
Explanation opens after your attempt
A. \(\sqrt{255}\) (15) और (16) के बीच है, \(\sqrt{257}\) (16) और (17) के बीच है\(\sqrt{255}\) lies between (15) and (16), \(\sqrt{257}\) lies between (16) and (17)
Concept
Since \(255<256=16^2\), \(\sqrt{255}<16\). Since (257>256), \(\sqrt{257}>16\).
Why this answer is correct
The correct answer is A. \(\sqrt{255}\) (15) और (16) के बीच है, \(\sqrt{257}\) (16) और (17) के बीच है / \(\sqrt{255}\) lies between (15) and (16), \(\sqrt{257}\) lies between (16) and (17). Since \(255<256=16^2\), \(\sqrt{255}<16\). Since (257>256), \(\sqrt{257}>16\).
Exam Tip
\(255<256=16^2\), इसलिए \(\sqrt{255}<16\)। (257>256), इसलिए \(\sqrt{257}>16\)।
