To find the value of the expression 7 + 3i + 2 + 6i, we will first combine the real parts and the imaginary parts separately.
1. Identify the real numbers: 7 and 2. When we add these together, we get:
- 7 + 2 = 9
2. Next, we look at the imaginary numbers: 3i and 6i. Adding these gives us:
- 3i + 6i = 9i
3. Now, we can combine the results from step 1 and step 2:
- The final result is 9 + 9i.
So, the value of the expression 7 + 3i + 2 + 6i is 9 + 9i.
