Correct Answer

A. \(\sqrt{2}\) का दशमलव लगभग (1.414) हैThe decimal of \(\sqrt{2}\) is approximately (1.414)

Step 1

Concept

A short decimal approximation does not prove irrationality.

Step 2

Why this answer is correct

A solid proof assumes rationality and derives a contradiction.

Step 3

Exam Tip

In exams, write logical proof instead of approximation. चरण 1: दशमलव का छोटा अनुमान अपरिमेयता सिद्ध नहीं करता। चरण 2: ठोस प्रमाण में परिमेय मानकर विरोधाभास निकाला जाता है। चरण 3: परीक्षा में अनुमान की जगह तार्किक प्रमाण लिखें।
