यदि \(A=\{1,2,3,4,6\}\) और \(R=\{(a,b):\operatorname{lcm}(a,b)=6\}\), तो कौन सा युग्म (R) में है?
If \(A=\{1,2,3,4,6\}\) and \(R=\{(a,b):\operatorname{lcm}(a,b)=6\}\), which pair belongs to (R)?
Explanation opens after your attempt
Correct Answer
A. ((2,3))
Concept
(\operatorname{lcm}(2,3)=6), so \((2,3)\in R\). In the other options, the \(\operatorname{lcm}\) is not (6).
Why this answer is correct
The correct answer is A. ((2,3)). (\operatorname{lcm}(2,3)=6), so \((2,3)\in R\). In the other options, the \(\operatorname{lcm}\) is not (6).
Exam Tip
(\operatorname{lcm}(2,3)=6), इसलिए \((2,3)\in R\) है। बाकी विकल्पों में \(\operatorname{lcm}\) (6) नहीं मिलता।
