INTRODUCTION TO LOGARITHMS

 

Logarithms are very useful mathematical entities that have an enormous amount of application to real-world situations. Combined with their inverse relationship to the exponential functions, logarithms allow for the simplification of complex problem situations to basic arithmetic operations.  In this unit you will examine the definition and inverse relationship with the exponential function, practice the laws of logarithms, solve logarithmic equations, and explore a more efficient method for solving equations using the “Change of Base” formula for logarithms.
