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.

What is the value of I squared?

What happens to the values of I when raised to powers that are multiples of 4?

Explain the process of finding I to the 25th power.

What is the significance of the remainder when simplifying powers of I?

How do you determine the remainder when dividing an exponent by 4?
