वर्गमूल सर्पिल में \(\sqrt{1680}\) और \(\sqrt{1681}\) की तुलना में कौन-सा निष्कर्ष सही है?
Which conclusion is correct when comparing \(\sqrt{1680}\) and \(\sqrt{1681}\) in a square root spiral?
Explanation opens after your attempt
A. \(\sqrt{1680}\) (40) और (41) के बीच है और \(\sqrt{1681}=41\) है\(\sqrt{1680}\) lies between (40) and (41), and \(\sqrt{1681}=41\)
Concept
\(40^2<1680<41^2\), and \(1681=41^2\). Therefore \(\sqrt{1681}\) is exactly (41).
Why this answer is correct
The correct answer is A. \(\sqrt{1680}\) (40) और (41) के बीच है और \(\sqrt{1681}=41\) है / \(\sqrt{1680}\) lies between (40) and (41), and \(\sqrt{1681}=41\). \(40^2<1680<41^2\), and \(1681=41^2\). Therefore \(\sqrt{1681}\) is exactly (41).
Exam Tip
\(40^2<1680<41^2\) और \(1681=41^2\) है। इसलिए \(\sqrt{1681}\) ठीक (41) है।
