Solution: Note that 1 6 = 6 1 and 36 = 62.Therefore the equation can be written 02/06/2018 · Okay, in this equation we’ve got three logarithms and we can only have two. So, we saw how to do this kind of work in a set of examples in the previous section so we just need to do the same thing here. It doesn’t really matter how we do this, but since one side already has one logarithm on it we might as well combine the logs on the other side.

Other Logarithmic Definitions: • Definition of Common Logarithm : Logarithms with a base of 10 are called common logarithms. It is customary to write ˜˜aT˜˜ . • Definition of Natural Logarithm: Logarithms with the base of U are called natural logarithms. It is customary to write V˜˜aT˜˜ . Sometimes a logarithm is written without a base, like this: log(100) This usually means that the base is really 10. It is called a "common logarithm". Engineers love to use it. On a calculator it is the "log" button. It is how many times we need to use 10 in a multiplication, to get our desired number.
