<u>Answer: </u>
<em>If set A = (3, 4, 7, 9) and if set D = (9, 4, 3, 7) , then </em><em>set A = set D</em><em> is </em><em>true</em><em>.</em>
<u>Solution: </u>
Two sets are said to be equal, if the elements in both the sets are exactly same.
From question, the given sets are
Set A = (3, 4, 7, 9)
Set D = (9, 4, 3, 7)
Set A and Set D contain same elements. In sets and relations, we need not worry about the elements positions. For the given set A the elements are {3,4,7,9} and for set D the elements are {9,4,3,7}. The elements are same each other irrespective of their positions. Hence, the given condition set A= set D is True.
