Is there an easy way to understand logarithmic functions?

I don't understand the form and the variables that are used. Can someone help me with this, maybe give me some examples and explain your way through them? It would help me a lot.

For any relation of three variables a, b and A such that A = b^a, a logarithmic function can be created.

`A = b^a`

=> `log_b A = a`

All the properties of logarithmic functions can be derived from the definition of the logarithmic function given above.

``Keep in mind that a logarithmic function has 3 parts. A number that is used as the base (b), a number (A) the log of which to the base (b) is being determined and the log of A to the base b that is equal to a. If the base is raised to the power of the value of the logarithm, the result is the number of which the logarithm is being determined or as stated earlier `log_b A = a` implies `A = b^a`
