Learn about the properties of logarithms that help us rewrite logarithmic expressions, and about the change of base rule that allows us to evaluate any logarithm we want using the calculator.

The graph of y = log 2 x is shown below. Which of the following is the graph of y = 3 log 2 (x 4) ?

Given a few points on the graph of an exponential function, Sal plots the corresponding points on the graph of the corresponding logarithmic function. Created by Sal Khan.

Logarithms are the inverses of exponents. They allow us to solve challenging exponential equations, and they are a good excuse to dive deeper into the relationship between a function …

We're asked to graph, y is equal to log base 5 of x. And just to remind us what this is saying, this is saying that y is equal to the power that I have to raise 5 to to get to x.

Sal explains what logarithms are and gives a few examples of finding logarithms.

Learn how to solve any exponential equation of the form a⋅b^ (cx)=d. For example, solve 6⋅10^ (2x)=48. The key to solving exponential equations lies in logarithms! Let's take a closer look by …
