Answer:
D. 18
Step-by-step explanation:
12.50 x 18 = 225
hope it helps :)
Then collect like terms
answer is x = 4
J = 9
12 - J = 3
12 - 3 = J
2 is the answer
i^223 = -i
i^113 = i
i^82 = -1
i^48 = 1
These are rules of i.
i^1 = i
i^2 = -1
i^3 = -i
i^4 = 1
You just have to apply this to the powers you are given.
