A real number
ok so
any even power is i^(2n) where n is a whole number
if n=1
i^2=(√-1)^2=-1
if i^3, then it is equal to (i^2)(i)=(-1)(i)=-i
if i^4, then it is equal to (i^2)(i^2)=(-1)(-1)=1
therefor
i^1=i
i^2=-1
i^3=-i
i^4=1
then it repeats
look at the odd powers
i and -i
they are complex
therefor
if i is raised to an odd power, it cannot be simplified to be a real number
What is the question you are trying to figure out?
The factor of x?
Find the ratio of two corresponding sides,
- if you start with the smaller figure, your answer will be less than one
- if you start with the larger figure, your answer will be greater than one
$ 1 U.S. dollar = 0.76 euros
so $ 30 U.S. dollars = (30 * 0.76) = 22.8 euros <==
