यदि \(A=\{0\}\) और \(B=\{1\}\) है, तो \(A\times B\) और \(B\times A\) के बारे में सही कथन कौन सा है?
If \(A=\{0\}\) and \(B=\{1\}\), which statement about \(A\times B\) and \(B\times A\) is correct?
Explanation opens after your attempt
A. \(A\times B={(0,1)}\) और \(B\times A={(1,0)}\)\(A\times B={(0,1)}\) and \(B\times A={(1,0)}\)
Concept
In \(A\times B\), (0) is first and (1) is second, while in \(B\times A\) the order is reversed. Order remains important even with one element in each set.
Why this answer is correct
The correct answer is A. \(A\times B={(0,1)}\) और \(B\times A={(1,0)}\) / \(A\times B={(0,1)}\) and \(B\times A={(1,0)}\). In \(A\times B\), (0) is first and (1) is second, while in \(B\times A\) the order is reversed. Order remains important even with one element in each set.
Exam Tip
\(A\times B\) में (0) पहले और (1) दूसरे स्थान पर है, जबकि \(B\times A\) में क्रम उल्टा है। एक-एक तत्व होने पर भी क्रम महत्वपूर्ण रहता है।
