melissa and tomas are playing a game with complex numbers. if melissa has a score of 5 - 4i and tomas has a score of 3 + 2i, what is their total score?\n8 - 6i\n8 + 6i\n8 - 2i\n8 + 2i
Answer
Explanation:
Step1: Add real - parts
Add the real parts of the two complex numbers: $5 + 3=8$.
Step2: Add imaginary - parts
Add the imaginary parts of the two complex numbers: $-4i+2i = (-4 + 2)i=-2i$.
Step3: Combine results
Combine the results of the real - part addition and the imaginary - part addition. The total complex number is $8-2i$.
Answer:
C. $8 - 2i$
