Correct Answer

A. परिमेय मानना, सरलतम भिन्न लिखना, वर्ग करना, साझा गुणनखंड से विरोधाभास लेनाAssume rational, write lowest-form fraction, square, take contradiction from common factor

Step 1

Concept

The proofs of \(\sqrt{2}\), \(\sqrt{3}\), and \(\sqrt{5}\) use contradiction.

Step 2

Why this answer is correct

First assume rationality, write a lowest-form fraction, and square.

Step 3

Exam Tip

Finally, a common factor gives contradiction. चरण 1: \(\sqrt{2}\), \(\sqrt{3}\), और \(\sqrt{5}\) के प्रमाण विरोधाभास विधि से होते हैं। चरण 2: पहले परिमेय मानकर सरलतम भिन्न लिखते हैं और वर्ग करते हैं। चरण 3: अंत में साझा गुणनखंड से विरोधाभास मिलता है।
