Simplify the expression using the definition of an imaginary number i = sqrt -1
i32 = 1
i25 = i
i86 = -1
i51 = -i
Im pretty sure its A, but dont count on me!!! i hope it helps :/
Here is your answer friend
You know if something is a function or not because the X will never be used twice in a set. If it is, then it's not a function.
A. Uses -1 twice
B. Uses Nothing twice (good)
C. Uses 0 twice
D. Uses 0 twice
B is your answer
