Question 1/1 Easy Mathematics Chapter 1: Real Numbers 6: Proof of irrationality of √2, √3, √5 Class 10 Level 16

यदि \(p^2\) सम है, तो (p) के बारे में कौन सा निष्कर्ष सही है?

If \(p^2\) is even, which conclusion about (p) is correct?

Explanation opens after your attempt
Correct Answer

A. (p) सम है(p) is even

Step 1

Concept

If the square of an integer is even, then the integer itself is even.

Step 2

Why this answer is correct

So if \(p^2\) is even, (p) is also even.

Step 3

Exam Tip

This small fact is very important in the proof of \(\sqrt{2}\). चरण 1: किसी पूर्णांक का वर्ग सम हो तो वह पूर्णांक भी सम होता है। चरण 2: इसलिए \(p^2\) सम होने पर (p) भी सम होगा। चरण 3: यह छोटी बात \(\sqrt{2}\) के प्रमाण में बहुत महत्वपूर्ण है।
