Understanding Exponents

The video tutorial introduces the concept of exponents, explaining how they represent repeated multiplication of the same number. It distinguishes between expanded and exponential forms, providing examples for clarity. Special terms like 'squared' and 'cubed' are discussed, and the video concludes with examples of calculating the values of exponential expressions.
