Simplify complex numbers

The video tutorial explains the concept of imaginary numbers, focusing on the imaginary unit 'i'. It describes how 'i' is defined as the square root of -1 and explores the powers of 'i', which follow a repeating pattern every four terms. The tutorial then demonstrates how to calculate 'i' to the 67th power by dividing 67 by 4 and using the remainder to determine the equivalent power of 'i'. The lesson concludes with encouragement for viewers to engage further with the material.
