For example the result for 2 x = 5 can be given as a logarithm, x = log 2 (5) . You will learn how to evaluate this logarithmic expression over the following lessons.

Mar 3, 2016 · What you will learn in this lesson Logarithms, like exponents, have many helpful properties that can be used to simplify logarithmic expressions and solve logarithmic …

Learn how to rewrite any logarithm using logarithms with a different base. This is very useful for finding logarithms in the calculator!

We also know that if we have a logarithm-- let me write it this way, actually-- if I have b times the log base a of c, this is equal to log base a of c to the bth power.

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.

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 …

Regardless of who you are, mastering even just one more skill on Khan Academy results in learning gains.

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

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

In this lesson, we will prove three logarithm properties: the product rule, the quotient rule, and the power rule. Before we begin, let's recall a useful fact that will help us along the way.
