यदि \(A=\{4\}\) और \(B=\{6\}\) है, तो \(A\times B\) में कितने तत्व होंगे?
If \(A=\{4\}\) and \(B=\{6\}\), how many elements are in \(A\times B\)?
Explanation opens after your attempt
Correct Answer
B. (1)
Concept
Both sets have one element each, so only ((4,6)) is formed. The product of singleton sets gives one ordered pair.
Why this answer is correct
The correct answer is B. (1). Both sets have one element each, so only ((4,6)) is formed. The product of singleton sets gives one ordered pair.
Exam Tip
दोनों समुच्चय में एक-एक तत्व है, इसलिए केवल ((4,6)) बनेगा। एकल समुच्चयों का गुणन एक क्रमित युग्म देता है।
