Simplifying an imaginary number to a higher power

The video tutorial covers the concept of imaginary numbers, focusing on the powers of i. It explains the repeating pattern of i's powers and demonstrates how to calculate higher powers using this pattern. An example of calculating i to the 54th power is provided, illustrating the method of dividing the exponent by 4 and using the remainder to find the equivalent power of i. The tutorial emphasizes understanding the first four powers of i and applying the repetition concept for simplification.

What does i to the 5th power equal?

What is the remainder when 54 is divided by 4?
