Let A = {2,4,6,8 },B = { 6,8,10 ,12} and C = {7,8,9,10 } Find .
` A uu B `

Answer

To find \( A \cup B \) (the union of sets A and B), we will follow these steps:

### Step 1: Identify the elements of sets A and B
- Set A = {2, 4, 6, 8}
- Set B = {6, 8, 10, 12}

### Step 2: Combine the elements of both sets
- We will list all the elements from both sets A and B.

### Step 3: Remove duplicates
- The elements 6 and 8 are present in both sets A and B. In a union, we only include each element once.

### Step 4: Write the final union set
- After combining and removing duplicates, we have:
- From A: 2, 4, 6, 8
- From B: 10, 12 (6 and 8 are already included)

Thus, the union \( A \cup B = \{2, 4, 6, 8, 10, 12\} \).

### Final Answer:
\( A \cup B = \{2, 4, 6, 8, 10, 12\} \)
