Correct Answer

B. \( \sqrt{8} \)

Step 1

Concept

Since \(2^2<8<3^2\), \( \sqrt{8} \) lies between (2) and (3). Since (8) is not a perfect square, it is irrational.

Step 2

Why this answer is correct

The correct answer is B. \( \sqrt{8} \). Since \(2^2<8<3^2\), \( \sqrt{8} \) lies between (2) and (3). Since (8) is not a perfect square, it is irrational.

Step 3

Exam Tip

\(2^2<8<3^2\) इसलिए \( \sqrt{8} \) (2) और (3) के बीच है। (8) पूर्ण वर्ग नहीं है इसलिए यह अपरिमेय है।
