यदि \(A={x:x\) (18) का अभाज्य गुणनखंड है(}) और \(B=\{2,3\}\) हैं तो कौन सा कथन सही है?
If \(A={x:x\) is a prime factor of (18)(}) and \(B=\{2,3\}\) then which statement is correct?
Explanation opens after your attempt
A. (A=B)
Concept
\(18=2\times3^2\), but (3) is written once in a set. Keep factorization and set counting separate.
Why this answer is correct
The correct answer is A. (A=B). \(18=2\times3^2\), but (3) is written once in a set. Keep factorization and set counting separate.
Exam Tip
\(18=2\times3^2\) है, पर समुच्चय में (3) एक बार लिखा जाता है। गुणनखंड और समुच्चय की गिनती अलग रखें।
