Required information Ch 02 Sec 2 Ex 16 MAIN - Properties of Set Operations NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Click and drag the steps on the left to their corresponding step number on the right to prove the given statement. Ch 02 Sec 2 Ex 16 (e) - Properties of Set Operations $A?(B?A)=A?B$ Step 1 Suppose that $x$ belongs to $A?(B?A)$. Step 2 Step 3 Then $x$ belong to either $A$ or $x$ belong to $B?A$. Which means, $x$ belong to $A$ and $x$ not belong to $B$. Which means, $x$ belong to $A$ or $x$ belong to $B$. Then we get, $x$ belongs to $A?B$ by the definition of union.
