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
Correct Answer

C. (16)

Step 1

Concept

(n(A)=4), so (n\(A\times A\)=4\times 4=16). With the same set, the count behaves like a square.

Step 2

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.

Step 3

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।
