Exponent Rules: Multiplication, Division, and Zero

The video tutorial reviews multiplication and division of expressions, focusing on expanding and simplifying them. It introduces rules for multiplying and dividing powers with the same base, emphasizing the use of invisible exponents. The tutorial also covers the concept of zero exponents and the importance of not dividing by zero. Students are encouraged to practice problems to reinforce their understanding.
