Answer:
Logarithmic .
Explanation:
When we evaluate the logarithmic expression then we prepared to work
with logarithmic function
If , I want to solve the logarithmic expression then first we should know about the logarithmic theorem rules .
If ,I don't know about the logarithmic rules then we can't evaluate the logarithmic expression.
So , first we should do practice with logarithmic function and we should know how to use of logarithmic rules during evaluating the logarithmic expression .
Logarithmic rules :



For example ; we have

Therefore, by using logarithmic rule then we get

Therefore, if i want to evaluate the logarithmic expresssion then i will be prepared to work with logarithmic function .
