This video tutorial explains the power rule of logarithms, which states that log base B of M raised to the power of n equals n times log base B of M. The tutorial demonstrates how to use this property to expand logarithms and write them with a coefficient of one. Examples include expanding log base 7 of X to the 5th and log base 2 of 81. The video also covers reversing the power rule to simplify logarithms, such as converting 3 natural log X to natural log X cubed. The tutorial emphasizes the importance of having a coefficient of one to apply other logarithmic properties.
