In this lesson on logarithms, we learn about the product property of logarithms and how to write expressions involving logs as a single log using the product property. We derive and prove the property and apply it to various examples, including how to rewrite a sum of logs as a single log and how to rewrite a product as a sum of logs. We also caution against the common mistake of trying to separate out a log of a subtraction or sum problem. Ultimately, this lesson provides a solid foundation for understanding the properties of logarithms and how to manipulate them.
In this video, we derive and prove the product property of logarithms and write expressions involving logs as a singe log using the product property.
