वर्गमूल सर्पिल में \(\sqrt{72}\) और \(\sqrt{81}\) के बारे में कौन-सा कथन सही है?
Which statement about \(\sqrt{72}\) and \(\sqrt{81}\) in a square root spiral is correct?
Explanation opens after your attempt
B. \(\sqrt{72}\) (8) और (9) के बीच है और \(\sqrt{81}=9\) है\(\sqrt{72}\) lies between (8) and (9), and \(\sqrt{81}=9\)
Concept
\(8^2<72<9^2\), and \(81=9^2\). Therefore \(\sqrt{81}\) equals (9).
Why this answer is correct
The correct answer is B. \(\sqrt{72}\) (8) और (9) के बीच है और \(\sqrt{81}=9\) है / \(\sqrt{72}\) lies between (8) and (9), and \(\sqrt{81}=9\). \(8^2<72<9^2\), and \(81=9^2\). Therefore \(\sqrt{81}\) equals (9).
Exam Tip
\(8^2<72<9^2\) और \(81=9^2\) है। इसलिए \(\sqrt{81}\) का मान (9) है।
