565 is the correct answer
Answer:
-13 -i
Step-by-step explanation:
The first step is to find the sum
5-9i and -4+7i
Add the real parts and then the imaginary parts
5+-4 = 1
-9i + 7i = -2i
5-9i + -4+7i = 1 -2i
Now we subtract 14 -3i
1 -2i - (14 -3i)
Subtract the real parts and then the imaginary parts
1-14 = -13
-2i - -3i = -2i+3i = i
1 -2i - (14 -3i) = -13 -i
= 512000000
