A comprehensive guide for learning all about logarithms with definitions, the rules or properties of logs, common and natural logs, negative logs, how to expand logs, solved examples, and practice questions.

The purpose of this task is to help students 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...

A set of examples and exercises that cover how to solve population problems by using exponents and logarithms.

This site explains The logarithm constant : log(2). It is a very comprehensive site.

The purpose of this task is to use technology to study the behavior of some exponential and logarithmic graphs and to manipulate some explicit logarithmic and exponential expressions. Aligns with HSF-LE.A.4, F-BF.B.5, and F-IF.C.7.e.

This animated video explores logarithms and explains how they are used in chemistry. Get the basics on these critical mathematical functions -- and discover why smart use of logarithms can determine whether your eyes turn red at the...

In this lesson, students will learn how exponents and logarithms are connected and how to evaluate logarithms.

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

The laws of logarithms (which flow directly out of the laws of exponents) are discussed here. Combining logs with the same base and the Change of Base Formula are also explained in straightforward language for the reader.

A set of examples and exercises that cover interest rate problems and how to solve them using exponents and logarithms.

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

The purpose of this task is to help students 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...

A 2-page reference that outlines the what a logarithm is, the rules of exponents and logs, and how to solve simple exponential and log equations.

A thorough treatment of the laws of logarithms, how they relate to the laws of exponents, and examples of each.

Solve word problems about exponential situations. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

A set of exercises, complete with solutions, covering the basics of exponential functions, from the laws of exponents to exponential growth and decay.

Purplemath contains about 40 different lessons on various algebra topics. The lessons are divided into five different sections: preliminary topics, beginning algebra, intermediate algebra, advanced algebra, and word problems. The lessons...
