Exponential identities and logarithms that are commonly used are listed on this page.

The connection between exponential and logarithmic functions is made clear through examples and practice exercises.

Exponential identities and logarithms that are commonly used are listed on this page.

The purpose of this task is to help learners see the "why" behind properties of logs that are familiar but often just memorized (and quickly forgotten or misremembered). The task focuses on the verbal definition of the log, helping...

The purpose of this task is to help learners see that the definition of the logarithm as an exponent results in an inverse relationship between the exponential and logarithm functions with the same base. This prepares them to think about...
