Pre-Calculus - Rewriting complex numbers to higher powers

12th - Higher Ed
In this video series I show you how to simplify complex numbers to a higher power. We notice that i raised to a power repeats itself after the 4th degree. So we will divide the power in the problem by 4 and use the remainder to simplify...
