यदि \(A=\{1,2,3\}\), \(B=\{3,6,9\}\) और \(C=\{6\}\) हैं, तो \(A\times(B-C)\) क्या होगा?
If \(A=\{1,2,3\}\), \(B=\{3,6,9\}\) and \(C=\{6\}\), what is \(A\times(B-C)\)?
Explanation opens after your attempt
A. ({(1,3),(1,9),(2,3),(2,9),(3,3),(3,9)})
Concept
(B-C={3,9}), so each element of (A) pairs with (3) and (9). Find the difference first and then write the pairs.
Why this answer is correct
The correct answer is A. ({(1,3),(1,9),(2,3),(2,9),(3,3),(3,9)}). (B-C={3,9}), so each element of (A) pairs with (3) and (9). Find the difference first and then write the pairs.
Exam Tip
(B-C={3,9}), इसलिए (A) के हर अवयव के साथ (3) और (9) जुड़ेंगे। पहले अंतर निकालें फिर युग्म लिखें।
