If \(A=\{1,2\}\), how many ordered pairs are there in \(A\times A\)?

Explanation opens after your attempt
Correct Answer

C. (4)

Step 1

Concept

If (n(A)=2), then (n\(A\times A\)=22=4). Use (n(A)2) while counting.

Step 2

Why this answer is correct

The correct answer is C. (4). If (n(A)=2), then (n\(A\times A\)=22=4). Use (n(A)2) while counting.

Step 3

Exam Tip

यदि (n(A)=2), तो (n\(A\times A\)=22=4)। संख्या गिनते समय (n(A)2) का प्रयोग करें।
