वर्गमूल सर्पिल में \(\sqrt{440}\) और \(\sqrt{442}\) की संख्या-रेखा स्थिति के बारे में सही कथन कौन-सा है?
Which statement about the number-line positions of \(\sqrt{440}\) and \(\sqrt{442}\) in a square root spiral is correct?
Explanation opens after your attempt
B. \(\sqrt{440}\) (20) और (21) के बीच है, \(\sqrt{442}\) (21) और (22) के बीच है\(\sqrt{440}\) lies between (20) and (21), \(\sqrt{442}\) lies between (21) and (22)
Concept
Since \(440<441=21^2\), \(\sqrt{440}<21\). Since (442>441), \(\sqrt{442}>21\).
Why this answer is correct
The correct answer is B. \(\sqrt{440}\) (20) और (21) के बीच है, \(\sqrt{442}\) (21) और (22) के बीच है / \(\sqrt{440}\) lies between (20) and (21), \(\sqrt{442}\) lies between (21) and (22). Since \(440<441=21^2\), \(\sqrt{440}<21\). Since (442>441), \(\sqrt{442}>21\).
Exam Tip
\(440<441=21^2\), इसलिए \(\sqrt{440}<21\)। (442>441), इसलिए \(\sqrt{442}>21\)।
