यदि \(A=\{2,4,6\}\) और \(B=\{6,8,10\}\) हैं, तो (\mathcal{P}\(A\cup B\)) में कितने तत्व होंगे?
If \(A=\{2,4,6\}\) and \(B=\{6,8,10\}\), how many elements will (\mathcal{P}\(A\cup B\)) have?
Explanation opens after your attempt
Correct Answer
B. (32)
Concept
\(A\cup B={2,4,6,8,10}\), so it has (5) elements. Hence its power set has \(2^5=32\) elements.
Why this answer is correct
The correct answer is B. (32). \(A\cup B={2,4,6,8,10}\), so it has (5) elements. Hence its power set has \(2^5=32\) elements.
Exam Tip
\(A\cup B={2,4,6,8,10}\) है इसलिए इसमें (5) तत्व हैं। अतः घात समुच्चय में \(2^5=32\) तत्व होंगे।
