यदि (n(P(A))=n(P(B))), तो कौन सा निष्कर्ष निश्चित रूप से सत्य है?
If (n(P(A))=n(P(B))), which conclusion is definitely true?
Explanation opens after your attempt
Correct Answer
B. (n(A)=n(B))
Concept
From (2^{n(A)}=2^{n(B)}), we get (n(A)=n(B)), but the sets need not be equal. Cardinality and equality are different ideas.
Why this answer is correct
The correct answer is B. (n(A)=n(B)). From (2^{n(A)}=2^{n(B)}), we get (n(A)=n(B)), but the sets need not be equal. Cardinality and equality are different ideas.
Exam Tip
(2^{n(A)}=2^{n(B)}) से (n(A)=n(B)) मिलता है, पर समुच्चय समान होना जरूरी नहीं। कार्डिनैलिटी और समानता अलग बातें हैं।
