Explanation opens after your attempt
Correct Answer

A. (x) सम है(x) is even

Step 1

Concept

If (x) were odd, then \(x^2\) would be odd.

Step 2

Why this answer is correct

Since \(x^2\) is given even, (x) must be even.

Step 3

Exam Tip

This rule is used immediately in the proof of \(\sqrt{2}\). चरण 1: यदि (x) विषम होता, तो \(x^2\) विषम होता। चरण 2: दिया है कि \(x^2\) सम है, इसलिए (x) सम होना चाहिए। चरण 3: \(\sqrt{2}\) के प्रमाण में यह नियम तुरंत काम आता है।
