Simplifying when you have imaginary numbers as your denominator

The video tutorial explains how to simplify mathematical expressions when the imaginary unit 'i' is in the denominator. It covers the concept of 'i' as the square root of -1, the process of rationalizing the denominator, and the steps to eliminate 'i' by multiplying both the numerator and denominator by 'i'. The tutorial concludes with a demonstration of simplifying expressions using these techniques.
