यदि \(A=\{3,6,9\}\), \(B=\{9,6,3,3\}\), तो कौन सा कथन सही है?
If \(A=\{3,6,9\}\), \(B=\{9,6,3,3\}\), which statement is correct?
Explanation opens after your attempt
B. (A=B)
Concept
In (B), (3) is written twice but counted once in a set.
Why this answer is correct
Both sets have actual elements (3,6,9).
Exam Tip
Repetition does not change equality. चरण 1: (B) में (3) दो बार लिखा है, पर समुच्चय में एक बार माना जाएगा। चरण 2: दोनों में वास्तविक तत्व (3,6,9) हैं। चरण 3: दोहराव समानता को नहीं बदलता।
