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 …

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.

This topic covers: - Radicals & rational exponents - Graphs & end behavior of exponential functions - Manipulating exponential expressions using exponent properties - Exponential …

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

The graph of y=log base 2 of x looks like a curve that increases at an ever-decreasing rate as x gets larger. It becomes very negative as x approaches 0 from the right. The graph of y=-log …

Radicals let us work backwards to get a base, but logarithms retrieve the exponent. The logarithmic properties may look new, but they're just the exponential properties in a new notation.

Joseph and Clarissa tried to solve the following logarithmic equation and found different solutions.

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 …

This unit develops your understanding of exponential and logarithmic functions as inverse relationships. You'll analyze their graphs, apply key properties to solve complex equations, …

I'm studying for a placement exam, and Sal's explanations of logarithms so far has been helpful. But how do we solve for algebraic equations with logarithms? Is there a video? Here is an …
