यदि \(A=\{1,2\}\) और \(B=\{2\}\) है, तो \(B\times A\) क्या होगा?
If \(A=\{1,2\}\) and \(B=\{2\}\), what is \(B\times A\)?
Explanation opens after your attempt
Correct Answer
B. ({(2,1),(2,2)})
Concept
In \(B\times A\), the first component is (2) from (B) and the second is (1) or (2) from (A). Reversing the order changes the answer.
Why this answer is correct
The correct answer is B. ({(2,1),(2,2)}). In \(B\times A\), the first component is (2) from (B) and the second is (1) or (2) from (A). Reversing the order changes the answer.
Exam Tip
\(B\times A\) में पहला घटक (B) से (2) होगा और दूसरा घटक (A) से (1) या (2) होगा। क्रम बदलने से उत्तर बदलता है।
