Remember, any logarithm of the form can be written in exponential form as

#1
So can be written as

------------
#2
Now to simplify , you can write the expression as


Now rewrite the log as an exponent

====>

So we can write the right side as since anything to the first power is itself.


So we then get:


Now since the bases are equal, the exponents are equal. In other words,


So going back to we can see that
