5. Logarithms of Exponents (Powers)
Logarithm of an exponential expression is equal with the exponent multiply with the base logarithm.
We know that:
When we change both sides of the above equality into logarithmic expressions with same base , we have:
(logarithm of products, [8], pg. 3)
Or we can write:
[13]

When , or we can write:

Example:
OR can be solved with a method below:
same result, two different methods of arriving to it
