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 dont know if its legal to do

any way i didnt study this logarithims of i (complex numbers)

so i dont think that this is the right way.

plz help
