कौन सा विकल्प (6) और (7) के बीच अपरिमेय संख्या है?
Which option is an irrational number between (6) and (7)?
Explanation opens after your attempt
B. \( \sqrt{43} \)
Concept
Since \(6^2<43<7^2\), \( \sqrt{43} \) lies between (6) and (7). Since (43) is not a perfect square, it is irrational.
Why this answer is correct
The correct answer is B. \( \sqrt{43} \). Since \(6^2<43<7^2\), \( \sqrt{43} \) lies between (6) and (7). Since (43) is not a perfect square, it is irrational.
Exam Tip
\(6^2<43<7^2\) इसलिए \( \sqrt{43} \) (6) और (7) के बीच है। (43) पूर्ण वर्ग नहीं है इसलिए यह अपरिमेय है।
