Pre-Calculus - Rewriting complex numbers to higher powers

The video tutorial explores the concept of the imaginary unit i and its powers. It demonstrates how to calculate and simplify powers of i, revealing a repeating pattern every four powers. The tutorial explains the importance of understanding this pattern for simplifying higher powers of i using modulo 4. Practical examples are provided to illustrate the application of this pattern, emphasizing the use of division and remainders to simplify complex expressions involving powers of i.
