यदि (n(A)=3) है, तो (n\(A\times A\)) कितना होगा?

If (n(A)=3), what is (n\(A\times A\))?

Explanation opens after your attempt
Correct Answer

C. (9)

Step 1

Concept

(n\(A\times A\)=n(A)n(A)=3\times 3=9). Even with the same set, the counts are multiplied.

Step 2

Why this answer is correct

The correct answer is C. (9). (n\(A\times A\)=n(A)n(A)=3\times 3=9). Even with the same set, the counts are multiplied.

Step 3

Exam Tip

(n\(A\times A\)=n(A)n(A)=3\times 3=9)। समान समुच्चय के साथ भी गुणा ही किया जाता है।
