Step 1: Identify the complex numbers to be added. The problem is to add (3+i4) and (-5-i8). Step 2: Group the real parts and the imaginary parts. When adding complex numbers, we add the real parts together and the imaginary parts together. The real parts are 3 and -5. The imaginary parts are i4 and -i8. Step 3: Add the real parts. 3 + (-5) = 3 - 5 = -2 Step 4: Add the imaginary parts. i4 + (-i8) = i4 - i8 = (4-8)i = -4i Step 5: Combine the results to form the final complex number. (3+i4) + (-5-i8) = (3-5) + (4-8)i = -2 - 4i The solution is: (3+i4) + (-5-i8) = -2 - 4i 3 done, 2 left today. You're making progress.
