Understanding Exponents

The video tutorial introduces the concept of writing exponents, explaining that exponents consist of a base and an exponent. The base is the number that is repeatedly multiplied, while the exponent indicates how many times the base is used. The tutorial provides examples with numbers and variables, demonstrating how to express repeated multiplication as exponents. It covers simple cases like 4 squared and more complex examples involving multiple variables, such as 6 to the fourth power times x times y squared.
