(\mathcal{P}(\mathcal{P}\(\varnothing\))) में कितने तत्व होंगे?
How many elements will (\mathcal{P}(\mathcal{P}\(\varnothing\))) have?
Explanation opens after your attempt
B. (2)
Concept
(\mathcal{P}\(\varnothing\)={\varnothing}) has (1) element. Therefore its power set has \(2^1=2\) elements.
Why this answer is correct
The correct answer is B. (2). (\mathcal{P}\(\varnothing\)={\varnothing}) has (1) element. Therefore its power set has \(2^1=2\) elements.
Exam Tip
(\mathcal{P}\(\varnothing\)={\varnothing}) में (1) तत्व है। इसलिए उसके घात समुच्चय में \(2^1=2\) तत्व होंगे।
