यदि \(A=\{0,1,2,3,4\}\) और (aRb) यदि \(a^2=b^2\), तो (R) में कितने ordered pairs हैं?
If \(A=\{0,1,2,3,4\}\) and (aRb) if \(a^2=b^2\), how many ordered pairs are in (R)?
Explanation opens after your attempt
A. (5)
Concept
All elements in the given set are non-negative, so \(a^2=b^2\) gives (a=b). Therefore only (5) diagonal pairs exist.
Why this answer is correct
The correct answer is A. (5). All elements in the given set are non-negative, so \(a^2=b^2\) gives (a=b). Therefore only (5) diagonal pairs exist.
Exam Tip
दिए गए समुच्चय में सभी अवयव अनऋण हैं, इसलिए \(a^2=b^2\) से (a=b) मिलता है। इसलिए केवल (5) diagonal युग्म हैं।
