Understanding Zero and Negative Exponents

This video tutorial covers the basics of zero and negative exponents. It explains that any number raised to the zero power equals one and provides examples to illustrate this concept. The tutorial also delves into negative exponents, explaining how they move terms from the numerator to the denominator and vice versa. Techniques for simplifying expressions with negative exponents are demonstrated, including handling complex problems. The video concludes with an invitation for viewers to ask questions and seek further help if needed.
