यदि \(A=\{r,s\}\) और \(B=\{u,v,w\}\) हैं, तो \(A\times B\) में दूसरे घटकों का समुच्चय क्या होगा?
If \(A=\{r,s\}\) and \(B=\{u,v,w\}\), what is the set of second components in \(A\times B\)?
Explanation opens after your attempt
Correct Answer
A. ({u,v,w})
Concept
Second components always come from (B). If (A) is non-empty, every element of (B) appears as a second component.
Why this answer is correct
The correct answer is A. ({u,v,w}). Second components always come from (B). If (A) is non-empty, every element of (B) appears as a second component.
Exam Tip
दूसरे घटक हमेशा (B) से आते हैं। यदि (A) रिक्त नहीं है तो (B) का हर अवयव दूसरे घटक के रूप में आएगा।
