Answer:
x = 0.8
Step-by-step explanation:
For this problem we will be using trigonometry :
I agree only if you have even powers -- even negative ones.
1/i^2 = 1/-1 = - 1
i^0 also gives 1 So far no problem.
It is when you consider the odd numbers that you don't get 1 or -1
You get either -i or i
i^(4n + 1) = i
i^(4n - 1) = -i
<span>The only statement that I can found in that problem is
-Subtract 8 from 80.
