Question

Let A and B be two sets, then open parentheses A union B close parentheses to the power of ´ end exponent union open parentheses A to the power of ´ end exponent intersection B close parenthesesis equal to

  1. A ''/>  
  2. A  
  3. B ''/>  
  4. None of these  

The correct answer is: A ´


    From Venn-Euler’s Diagram it is clear that

    open parentheses A union B close parentheses to the power of ´ end exponent union open parentheses A to the power of ´ end exponent intersection B close parentheses equals A ´
