Question

For any two sets $A$ and $B$ , $A minus left parenthesis A minus B right parenthesis$ equals

$A$
$A - B$
$A \cap B$
$A^{C} \cap B^{C}$

The correct answer is: $A intersection B$

Now, $A minus open parentheses A minus B close parentheses equals A minus left parenthesis A minus B to the power of C end exponent right parenthesis$
$equals A intersection open parentheses A intersection B to the power of C end exponent close parentheses to the power of C end exponent$
$equals A intersection left parenthesis A to the power of C end exponent union B right parenthesis$
$equals open parentheses A intersection A to the power of C end exponent close parentheses union left parenthesis A intersection B right parenthesis$
$equals A intersection B$
