कौन सा विकल्प (5) और (6) के बीच अपरिमेय संख्या है?
Which option is an irrational number between (5) and (6)?
Explanation opens after your attempt
B. \( \sqrt{31} \)
Concept
Since \(5^2<31<6^2\), \( \sqrt{31} \) lies between (5) and (6). Since (31) is not a perfect square, it is irrational.
Why this answer is correct
The correct answer is B. \( \sqrt{31} \). Since \(5^2<31<6^2\), \( \sqrt{31} \) lies between (5) and (6). Since (31) is not a perfect square, it is irrational.
Exam Tip
\(5^2<31<6^2\) इसलिए \( \sqrt{31} \) (5) और (6) के बीच है। (31) पूर्ण वर्ग नहीं है इसलिए यह अपरिमेय है।
