Simplify complex numbers

The video tutorial explains how to simplify imaginary numbers, focusing on the properties and powers of the imaginary unit 'i'. It covers the cyclical nature of i's powers, showing that every fourth power returns to 1. The tutorial provides a method to simplify higher powers of i by dividing the exponent by 4 and using the remainder to determine the result. This approach is applied to solve problems involving powers of i, emphasizing the repeating cycle and simplification techniques.
