Simplifying imaginary numbers to a higher power

The video tutorial explains how to express powers of the imaginary unit 'i' using remainders. It covers the cycle of powers of i, showing that i^1 = i, i^2 = -1, i^3 = -i, and i^4 = 1, and how this cycle repeats. The tutorial demonstrates how to use division and remainders to simplify calculations of higher powers of i, providing examples and practical applications. The method involves dividing the exponent by 4 and using the remainder to determine the equivalent power of i.
