The question requires adding and subtracting complex numbers, resulting in 4 - 13i after combining like terms from the real and imaginary parts.
The student's question involves adding and subtracting complex numbers. To compute (-3-8i)-(-7+2i)+(7-3i), we can break it into real and imaginary parts and then combine like terms. Here's the step-by-step calculation:
- Add/subtract real parts: (-3) - (-7) + 7 = 7 - 3 = 4
- Add/subtract imaginary parts: (-8i) - (2i) + (-3i) = -8i - 2i - 3i = -13i
So the answer is 4 - 13i.
