Easy Mathematics Chapter 1: Real Numbers Class 10 Level 18

\(\sqrt{2}\) के प्रमाण में यदि \(q^2=2k^2\) मिल जाए, तो (q) के बारे में क्या निष्कर्ष होगा?

In the proof of \(\sqrt{2}\), if \(q^2=2k^2\) is obtained, what conclusion follows about (q)?

Correct Answer

A. (q) सम है(q) is even

Step 1

Concept

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

Step 2

Why this answer is correct

If the square of an integer is even, the integer is also even.

Step 3

Exam Tip

So (q) is even, which helps form the contradiction. चरण 1: \(q^2=2k^2\) से \(q^2\) (2) से विभाज्य है। चरण 2: यदि किसी पूर्णांक का वर्ग सम है, तो वह पूर्णांक भी सम होता है। चरण 3: इसलिए (q) सम मिलेगा और यही विरोधाभास बनाने में मदद करता है।
