Easy Mathematics Chapter 1: Real Numbers Class 10 Level 16

(p=2k) को \(p^2=2q^2\) में रखने पर कौन सा निष्कर्ष मिलता है?

What conclusion is obtained by putting (p=2k) in \(p^2=2q^2\)?

Explanation opens after your attempt
Correct Answer

A. \(q^2=2k^2\), इसलिए \(q^2\) सम है\(q^2=2k^2\), so \(q^2\) is even

Step 1

Concept

If (p=2k), then \(p^2=4k^2\).

Step 2

Why this answer is correct

From \(4k^2=2q^2\), we get \(q^2=2k^2\), so \(q^2\) is even.

Step 3

Exam Tip

Simplify step by step to avoid mistakes. चरण 1: (p=2k) रखने पर \(p^2=4k^2\) होगा। चरण 2: \(4k^2=2q^2\) से \(q^2=2k^2\), इसलिए \(q^2\) सम है। चरण 3: धीरे-धीरे सरलीकरण करें ताकि गलती न हो।
