Correct Answer

B. \( \sqrt{43} \)

Step 1

Concept

Since \(6^2<43<7^2\), \( \sqrt{43} \) lies between (6) and (7). Since (43) is not a perfect square, it is irrational.

Step 2

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.

Step 3

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।
