Correct Answer

A. यह अपरिभाषित हैIt is undefined

Step 1

Concept

For \(x=\sqrt{2}\), \(x^2=2\).

Step 2

Why this answer is correct

The denominator \(x^2-2=0\), so the fraction is undefined.

Step 3

Exam Tip

Before evaluating a fraction, always check whether the denominator becomes zero. चरण 1: \(x=\sqrt{2}\) होने पर \(x^2=2\)। चरण 2: हर \(x^2-2=0\) हो जाता है, इसलिए भिन्न अपरिभाषित है। चरण 3: भिन्न का मान निकालने से पहले हर शून्य तो नहीं, यह जरूर जाँचें।
