\(यदि (A={x:x\) is a factor of \(10}) और (B={x:x\) is a factor of \(15}) हैं, तो (A\cup B) क्या है\)?
\(If (A={x:x\) is a factor of \(10}) and (B={x:x\) is a factor of \(15}), what is (A\cup B)\)?
Explanation opens after your attempt
Correct Answer
A. ( {1,2,3,5,10,15} )
Concept
\(A=\{1,2,5,10\}\) and \(B=\{1,3,5,15\}\). The union contains all distinct elements ({1,2,3,5,10,15}).
Why this answer is correct
The correct answer is A. ( {1,2,3,5,10,15} ). \(A=\{1,2,5,10\}\) and \(B=\{1,3,5,15\}\). The union contains all distinct elements ({1,2,3,5,10,15}).
Exam Tip
\(A=\{1,2,5,10\}\) और \(B=\{1,3,5,15\}\) है। संघ में सभी अलग-अलग अवयव ({1,2,3,5,10,15}) होंगे।
