यदि \(A=\{1,3,5\}\) और \(B=\{0,2\}\) हैं, तो \(A\times B\) के कितने उपसमुच्चय होंगे?
If \(A=\{1,3,5\}\) and \(B=\{0,2\}\), how many subsets does \(A\times B\) have?
Explanation opens after your attempt
Correct Answer
A. \(2^6\)
Concept
(n\(A\times B\)=3\times2=6), so the number of subsets is \(2^6\). Use \(2^n\) for counting subsets.
Why this answer is correct
The correct answer is A. \(2^6\). (n\(A\times B\)=3\times2=6), so the number of subsets is \(2^6\). Use \(2^n\) for counting subsets.
Exam Tip
(n\(A\times B\)=3\times2=6), इसलिए उपसमुच्चयों की संख्या \(2^6\) है। उपसमुच्चय गिनने में \(2^n\) लगाएं।
