यदि \(\sqrt{k}\) संख्या (7) और (8) के बीच है, तो (k) के लिए कौन-सा मान संभव है?
If \(\sqrt{k}\) lies between (7) and (8), which value of (k) is possible?
Explanation opens after your attempt
C. (57)
Concept
Since (49<57<64), \(7<\sqrt{57}<8\). Decide square-root bounds using squares.
Why this answer is correct
The correct answer is C. (57). Since (49<57<64), \(7<\sqrt{57}<8\). Decide square-root bounds using squares.
Exam Tip
क्योंकि (49<57<64), इसलिए \(7<\sqrt{57}<8\)। वर्गमूल की सीमा वर्गों से तय करें।
