Imaginary Numbers: Simplifying Large Exponents

You may learn imaginary numbers in Algebra 1, Algebra 2, or College Algebra. Many students can be intimidated by these. (“What the heck is an imaginary number??”) However, fear not, they’re really not bad! Today we’ll be looking at imaginary numbers with large exponents. By learning one simple strategy, you’ll be very comfortable with simplifying any imaginary number!

In the video I explain how to simplify imaginary numbers with large exponents by using the fact that i^2 = -1. First we’ll go over a few small exponents to get the hang of it, and then we’ll do four problems with large exponents.

Take five minutes to watch and you’ll be a pro! Then remember to share the love and knowledge with a classmate who could benefit 🙂
