\(यदि (A={x:x\in \mathbb{N},x\) is a factor of \(12}) और (B={1,2,3,5}) है, तो (A\cap B) क्या है\)?
\(If (A={x:x\in \mathbb{N},x\) is a factor of \(12}) and (B={1,2,3,5}), what is (A\cap B)\)?
Explanation opens after your attempt
Correct Answer
A. ( {1,2,3} )
Concept
\(A=\{1,2,3,4,6,12\}\), and the common part with (B) is ({1,2,3}). List the factor set first.
Why this answer is correct
The correct answer is A. ( {1,2,3} ). \(A=\{1,2,3,4,6,12\}\), and the common part with (B) is ({1,2,3}). List the factor set first.
Exam Tip
\(A=\{1,2,3,4,6,12\}\) है और (B) के साथ सामान्य भाग ({1,2,3}) है। गुणनखंड वाले समुच्चय को पहले लिखें।
