Question

how do you simplify i^123

Answer 1

\(\large\color{blue}{ \rm i^{123}=i^{120+3}=i^{120}\times i^3=i^3=? }\)

Answer 2

method 2
take the integer remainder when you divide \(123\) by \(4\)
since \(4\) goes in to \(120\) evenly the remainder is \(3\) so \(i^3\)
this is exactly the same as @SolomonZelman method just without writing it down

Answer 3

i^3 = i^2 * i = ?
