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 …

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.

In a base ten logarithmic scale, 2 cm on the scale corresponds to 10² (100). 3 cm corresponds to 10³ (1000). Obviously, if we change the base of the logarithm, the spacing between each …

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

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 …

Logarithms were originally used to facilitate calculations before modern calculators existed. Logarithms made it easier to perform difficult operations, e.g. find the value of 4th root of 24, …
