यदि \(A=\{-2,-1,0,1,2\}\) और (aRb) यदि \(a^2=b^2\), तो (R) में कौन सा ordered pair होगा?
If \(A=\{-2,-1,0,1,2\}\) and (aRb) if \(a^2=b^2\), which ordered pair will be in (R)?
Explanation opens after your attempt
A. ((-2,2))
Concept
Since ((-2)2=22=4), \((-2,2)\in R\). In square conditions, also check opposite signs.
Why this answer is correct
The correct answer is A. ((-2,2)). Since ((-2)2=22=4), \((-2,2)\in R\). In square conditions, also check opposite signs.
Exam Tip
क्योंकि ((-2)2=22=4), इसलिए \((-2,2)\in R\)। वर्ग वाली शर्त में विपरीत चिह्न भी जांचें।
