Question

Let A and B be two sets, then $left parenthesis A union B right parenthesis to the power of straight prime union open parentheses A to the power of straight prime intersection B close parentheses$ is equal to

$A^{'}$
A
B'
None of these

The correct answer is: $A to the power of straight prime$

From Venn-Euler’s Diagram it is clear that

$left parenthesis A union B right parenthesis to the power of straight prime union open parentheses A to the power of straight prime intersection B close parentheses equals A to the power of straight prime$
