यदि \(A=\{-2,-1,1,2\}\) और \(R=\{(a,b):a^2=b^2\}\) है, तो ([-2]) तुल्यता वर्ग क्या होगा?

If \(A=\{-2,-1,1,2\}\) and \(R=\{(a,b):a^2=b^2\}\), what is the equivalence class ([-2])?

Explanation opens after your attempt
Correct Answer

A. ({-2,2})

Step 1

Concept

Since ((-2)2=22), (-2) and (2) are in the same class. While forming a class, choose elements giving the same value.

Step 2

Why this answer is correct

The correct answer is A. ({-2,2}). Since ((-2)2=22), (-2) and (2) are in the same class. While forming a class, choose elements giving the same value.

Step 3

Exam Tip

((-2)2=22), इसलिए (-2) और (2) एक ही वर्ग में हैं। वर्ग बनाते समय समान मान देने वाले अवयव चुनें।
