Remember
i²=-1 so
i³=-i
i⁴=1
so
5i⁴+2i³+8i²-4
5(1)+2(-i)+8(-1)-4
5-2i-8-4
-7-2i is the form

Answer:2.9235
Step-by-step explanation:
Since 20 people are administered the medicine and;
11% of the 20 people suffer severe i.e 11% of 20 = 2.2 people
20% of them suffer moderate i.e
20% of 20 = 4 people and;
69% of the 20 people suffer minor side i.e
69% of 20 = 13.8 people
Therefore the probability 2, 4, and 14 people will suffer severe, moderate, or minor side effects, respectively will be;
2/2.2 + 4/4 + 14/13.8 (i.e possible outcome/total outcome)
This will give us 2.9235
