![]() For instance, the expression log7(3) + log7(x) can be combined by using the Product Rule to get log7(3×x) log7(3x). ![]() 14 ) log 7 log 12 21 ) 4log 6 + 3log 9 15 ) log 8 + log 3 22 ) 4log. To condense logarithms, we use log rules to combine separate logarithmic terms. You cannot cancel expressions that you are taking the log of and expressions outside of the logarithm.

We are open to collaborations of all types, please contact Andy at for all enquiries. More examples of condensing logarithms are in the following video. In our next example, we show how to simplify a more complex logarithm by condensing it. In our next example, we show how to simplify a more complex logarithm by condensing it. The word 'logarithm' was invented by John Napier in 1614. In this case, you could translate it as 'ratio' or 'proportion'. Logos () is a rather curious Greek word with multiple meanings. Here is the rule, just in case you forgot. Since we want to transform the left side into a single logarithmic equation, we should use the Product Rule in reverse to condense it. ![]() Write log3(5)+log3(8)log3(2) l o g 3 ( 5) + l o g 3 ( 8) l o g 3 ( 2) as a single logarithm. Logarithm is based on the combination of two Greek words: logos and arithmos (number). Example 1: Solve the logarithmic equation. The clear explanations, strong visuals mixed with dry humor regularly get millions of views. In our first example, we only need to apply the product rule and quotient rule to condense the expression.
