Roots & logarithms properties

First I'll introduce the roots. In this post root includes roots and potency.

A potency is an operation where you obtain a number that results of multiplying the base by himself a number of times equal to the index value.

In this example 5 is the base and 3 is the index:
 The root is the oposite operation of the potency. We can express a root like:
This type of calculus has its own properties:


I'll use "*" instead of "x" or "." to avoid misunderstandings. N and M are coefficients that can be fractions or integer numbers. Now I'm going to make an example:

Now the logarithm properties. First of all there is no solution in logarithms for negative numbers, That is it, so you don't need to calculate:

The logarithm is the inverse operation of the potency and you can calculate its solution by solving the next equation:

The solution of the logarithm is "b", that is the number to which we have to raise "a" in order to obtain "x".

And logarithms have a few properties:


An example:
