5n*[(2i)^(n-1) ]=11520
n=?
the answer in the book is n=9
notice i = (-1)^0.5
how do i solve this equation
i tried to solve it in many ways including logarithims
but log and i (complex numbers)
i don't know if its legal to do
any way i didnt study this logarithims of i (complex numbers)
so i don't think that this is the right way.
please help
