वर्गमूल सर्पिल में \(\sqrt{440}\) और \(\sqrt{441}\) की तुलना में कौन-सा निष्कर्ष सही है?
Which conclusion is correct when comparing \(\sqrt{440}\) and \(\sqrt{441}\) in a square root spiral?
Explanation opens after your attempt
A. \(\sqrt{440}\) (20) और (21) के बीच है और \(\sqrt{441}=21\) है\(\sqrt{440}\) lies between (20) and (21), and \(\sqrt{441}=21\)
Concept
\(20^2<440<21^2\), and \(441=21^2\). Therefore \(\sqrt{441}\) is exactly at (21).
Why this answer is correct
The correct answer is A. \(\sqrt{440}\) (20) और (21) के बीच है और \(\sqrt{441}=21\) है / \(\sqrt{440}\) lies between (20) and (21), and \(\sqrt{441}=21\). \(20^2<440<21^2\), and \(441=21^2\). Therefore \(\sqrt{441}\) is exactly at (21).
Exam Tip
\(20^2<440<21^2\) और \(441=21^2\) है। इसलिए \(\sqrt{441}\) ठीक (21) पर है।
