<h3>What is a logarithmic function?</h3>
A logarithmic function is modeled by:
It means that:
In this problem, we have that:
Applying the power property:
Applying the definition:
As the logarithm function is defined only for positive values, the correct statement is:

Answer: 9b - 8b
Step-by-step explanation:
ou need two factors that you will multiply together to give you -72b^2 and at the same time when you add this two factors it will give you + b . Check; 9b X -8b = -72b^2 and 9b + (-8b) = b , that is why 9b and -8b are the factors and they will replace the middle value
