Find the Union of the Sets B=(1,2,3,4) , A=(7,6,9)

Problem

A∪B* where *A={7,6,9},B={1,2,3,4}

Solution

1. Identify the elements of each set. Set A contains the elements {7,6,9} and set B contains the elements {1,2,3,4}

2. Apply the definition of the union of two sets, which is the set containing all elements that are in A in B or in both.

3. Combine the elements from both sets into a single set, ensuring no duplicates are listed.

4. Order the elements numerically for clarity.

Final Answer

A∪B={1,2,3,4,6,7,9}
