Which statement is correct when comparing \(\sqrt{72}\) and \(\sqrt{81}\) in a square root spiral?
Explanation opens after your attempt
Correct Answer
A. \(\sqrt{72}\) (8) और (9) के बीच है और \(\sqrt{81}=9\)\(\sqrt{72}\) is between (8) and (9) and \(\sqrt{81}=9\)
Concept
\(8^2<72<9^2\) and \(81=9^2\). Therefore the statement is correct.
Why this answer is correct
The correct answer is A. \(\sqrt{72}\) (8) और (9) के बीच है और \(\sqrt{81}=9\) / \(\sqrt{72}\) is between (8) and (9) and \(\sqrt{81}=9\). \(8^2<72<9^2\) and \(81=9^2\). Therefore the statement is correct.
Exam Tip
\(8^2<72<9^2\) और \(81=9^2\) है। इसलिए कथन सही है।
