Answer: Explanation below.
Step-by-step explanation:
First of all you need to know how to convert a logarithm into an exponential expression. The property is:
This is the same as:
Example 1:
We are trying to find what to raise 9 to, in order to get a result of 9.
When you have same bases, you equal exponents.
Therefore;
Example 2:
In this case, we have to make sure both sides have the same base. 32 can have a base of 2 if expressed as: which is 2*2*2*2*2
Rewriting this example we have;
Since we have the same base, we equal exponents.
Therefore;
Example 3:
729 can have a base of 3 if expressed as:
