Medium Mathematics Chapter 1: Real Numbers Class 10 Level 18

\(\sqrt{2}\) के प्रमाण में \(q^2=2k^2\) मिलने का महत्व क्या है?

What is the importance of getting \(q^2=2k^2\) in the proof of \(\sqrt{2}\)?

Correct Answer

A. इससे (q) भी सम सिद्ध होता हैIt proves (q) is also even

Step 1

Concept

From \(q^2=2k^2\), \(q^2\) is even.

Step 2

Why this answer is correct

If a square is even, the original integer is even.

Step 3

Exam Tip

(p) was already even and (q) is also even, creating contradiction. चरण 1: \(q^2=2k^2\) से \(q^2\) सम है। चरण 2: वर्ग सम हो तो मूल पूर्णांक सम होता है। चरण 3: (p) पहले सम था और (q) भी सम मिला, यही विरोधाभास बनाता है।
