यदि \(A=\{p,q,r\}\) है और \(A\times A\) बनाया जाता है, तो इसमें कितने क्रमित युग्म होंगे?
If \(A=\{p,q,r\}\) and \(A\times A\) is formed, how many ordered pairs will it contain?
Explanation opens after your attempt
Correct Answer
A. (9)
Concept
(n\(A\times A\)=n(A)2=32=9). In \(A\times A\), pairs with equal elements are also included.
Why this answer is correct
The correct answer is A. (9). (n\(A\times A\)=n(A)2=32=9). In \(A\times A\), pairs with equal elements are also included.
Exam Tip
(n\(A\times A\)=n(A)2=32=9) होता है। \(A\times A\) में समान अवयव वाले युग्म भी शामिल होते हैं।
