The problems in this lesson involve zero and negative exponents. For example, x^(-2) can be written as 1/x^2, which can serve as a kind of negative exponents definition: if we have x to a negative power, we can change it to 1 over x to the positive version of that power. Students also learn how to do problems that incorporate the product rule, quotient rule, and power rule in conjunction with zero and negative exponents. Finally, students learn how to deal with negative exponents in the denominator of a fraction. No negative exponents calculator is required, and a self-test serves as an interactive negative exponents worksheet.
