यदि \(A=\{6\}\) और \(B=\{9\}\) हैं, तो \(A\times B\) और \(B\times A\) कौन से हैं?
If \(A=\{6\}\) and \(B=\{9\}\), what are \(A\times B\) and \(B\times A\)?
Explanation opens after your attempt
Correct Answer
A. \(A\times B={(6,9)}\) और \(B\times A={(9,6)}\)\(A\times B={(6,9)}\) and \(B\times A={(9,6)}\)
Concept
In \(A\times B\), (6) is first and (9) is second. In \(B\times A\), the order is reversed.
Why this answer is correct
The correct answer is A. \(A\times B={(6,9)}\) और \(B\times A={(9,6)}\) / \(A\times B={(6,9)}\) and \(B\times A={(9,6)}\). In \(A\times B\), (6) is first and (9) is second. In \(B\times A\), the order is reversed.
Exam Tip
\(A\times B\) में (6) पहले और (9) दूसरे स्थान पर है। \(B\times A\) में क्रम उल्टा हो जाता है।
