Find A U { }. If A is any given set

A U { } = A

Step-by-step explanation:

Union is one of the operations that are performed on sets. In union, the elements of involved sets are combined and repetitive elements are removed (written only once)

Given

 A U { } = ?

Whenever union will be taken of any set and empty set the answer will be the set.

Similarly, when union of set A will be taken with empty set the result will be set A.

Hence,

A U { } = A
