Simplify i by using rules of exponents when i is raised to a higher power

The video tutorial explains how to simplify expressions involving imaginary numbers, specifically focusing on powers of the imaginary unit 'I'. It begins by introducing the concept of simplifying expressions and the importance of understanding the properties of exponents. The tutorial then demonstrates how to simplify 'I' raised to the 13th power by using the property that 'I' to the 4th power equals 1. The process involves breaking down the power into multiples of 4 and using exponent rules to simplify the expression. The video concludes with a summary of the steps and emphasizes the use of imaginary numbers in simplification.
