Question

6 Σ (12 – 4 i) i = 3

Answer 1

Answer:

- 24

Step-by-step explanation:

We have to get the value of the following sum as given.

$\sum_{3}^{6} (12-4i)$

This can be written in language as the summation of (12 -4i) where value of i ranges from 3 to 6.

$\sum_{3}^{6} (12-4i)$

= [12 - 4(3)] + [12 - 4(4)] + [12 - 4(5)] + [12 - 4(6)]

= 0 + [- 4] + [- 8] + [- 12]  

= - 24 (Answer)
