यदि \(A=\{1,2,3,4\}\) है, तो (n\(A\times A\)) कितना होगा?
If \(A=\{1,2,3,4\}\), what is (n\(A\times A\))?
Explanation opens after your attempt
C. (16)
Concept
(n(A)=4), so (n\(A\times A\)=4\times 4=16). With the same set, the count behaves like a square.
Why this answer is correct
The correct answer is C. (16). (n(A)=4), so (n\(A\times A\)=4\times 4=16). With the same set, the count behaves like a square.
Exam Tip
(n(A)=4), इसलिए (n\(A\times A\)=4\times 4=16)। समान समुच्चय होने पर भी संख्या वर्ग की तरह आती है।
