This video explains how to use the power rule to find derivatives of polynomials. It explains how finding derivatives is simpler using this approach. It the uses three examples to demonstrate its use. The first include x terms with exponents of1 and greater than one it also explains what do do with constants. The second explain explains how to use the power rule to find derivatives of polynomials with negative exponents. The third example shows how to find derivatives using the power rule for polynomials with fractional exponents.
