Answer:
- 24
Step-by-step explanation:
We have to get the value of the following sum as given.
[tex]\sum_{3}^{6} (12-4i)[/tex]
This can be written in language as the summation of (12 -4i) where value of i ranges from 3 to 6.
[tex]\sum_{3}^{6} (12-4i)[/tex]
= [12 - 4(3)] + [12 - 4(4)] + [12 - 4(5)] + [12 - 4(6)]
= 0 + [- 4] + [- 8] + [- 12]
= - 24 (Answer)
