Using negative exponents to avoid using quotient rule to take the derivative

The video tutorial explains how to handle expressions with negative powers. It begins by introducing the concept of negative exponents and proceeds to derive the expression for Y prime, which initially includes a negative exponent. The tutorial then demonstrates how to simplify the expression to avoid negative exponents, ultimately rewriting Y prime with a positive exponent. The instructor emphasizes a preference for using positive exponents in mathematical expressions.
