यदि (A) में (m) अवयव और (B) में (n) अवयव हैं, तो \(A\times B\) के उपसमुच्चयों की संख्या क्या होगी?
If (A) has (m) elements and (B) has (n) elements, how many subsets does \(A\times B\) have?
Explanation opens after your attempt
C. \(2^{mn}\)
Concept
\(|A\times B|=mn\), so the number of subsets is \(2^{mn}\). First find the cardinality of the base set.
Why this answer is correct
The correct answer is C. \(2^{mn}\). \(|A\times B|=mn\), so the number of subsets is \(2^{mn}\). First find the cardinality of the base set.
Exam Tip
\(|A\times B|=mn\), इसलिए इसके उपसमुच्चयों की संख्या \(2^{mn}\) होगी। पहले मूल समुच्चय की कार्डिनलिटी निकालें।
