यदि \(A=\{a,b\}\) और \(B=\{c\}\) हैं, तो \(B\times A\) कौन सा है?
If \(A=\{a,b\}\) and \(B=\{c\}\), which is \(B\times A\)?
Explanation opens after your attempt
Correct Answer
B. ({(c,a),(c,b)})
Concept
In \(B\times A\), the first component is (c) from (B), and the second is (a) or (b) from (A). Reversed order gives a different answer.
Why this answer is correct
The correct answer is B. ({(c,a),(c,b)}). In \(B\times A\), the first component is (c) from (B), and the second is (a) or (b) from (A). Reversed order gives a different answer.
Exam Tip
\(B\times A\) में पहला घटक (B) से (c) और दूसरा घटक (A) से (a) या (b) होगा। उल्टा क्रम अलग उत्तर देता है।
