यदि \(A=\{a,b,c\}\), \(B=\{1,2\}\) और \(C=\{p,q,r,s\}\) हैं, तो (n(\(A\times B\)\times C)) कितना होगा?
If \(A=\{a,b,c\}\), \(B=\{1,2\}\), and \(C=\{p,q,r,s\}\), what is (n(\(A\times B\)\times C))?
Explanation opens after your attempt
Correct Answer
C. (24)
Concept
(n\(A\times B\)=3\cdot2=6) and then \(6\cdot4=24\). An ordered pair is treated as one element in the next Cartesian product.
Why this answer is correct
The correct answer is C. (24). (n\(A\times B\)=3\cdot2=6) and then \(6\cdot4=24\). An ordered pair is treated as one element in the next Cartesian product.
Exam Tip
(n\(A\times B\)=3\cdot2=6) और फिर \(6\cdot4=24\)। युग्म का तत्व भी अगले कार्तीय गुणन में एक तत्व माना जाता है।
