Answer:
E = {9, 4, 7, 3}
Explanation:
If two sets are equal, then they have the same number of elements and the same elements.
The given set is A = {3, 4, 7, 9}
The set that has the same elements as A is E = {9, 4, 7, 3}
The two set have the elements 3, 4, 7, 9.
Over here the order does not matter.
