Correct Answer
C. (9)
Concept
\(|A\times A|=|A|\times |A|=3\times3=9\). In exams, use the square of the number of elements for \(A\times A\).
Why this answer is correct
The correct answer is C. (9). \(|A\times A|=|A|\times |A|=3\times3=9\). In exams, use the square of the number of elements for \(A\times A\).
Exam Tip
\(|A\times A|=|A|\times |A|=3\times3=9\)। परीक्षा में \(A\times A\) के लिए वर्ग संख्या लें।
