Pre-Calculus - What is change of base and how do we apply it

The video tutorial explains the change of base formula for logarithms, demonstrating how to solve logarithmic equations when calculators are limited to base 10. It provides examples, such as log base 5 of 25 and log base 3 of 27, and shows how to apply the change of base formula to solve these problems using any base. The tutorial emphasizes understanding the formula's application and overcoming calculator limitations.

Explain how to use a calculator to evaluate logarithms when the base is not 10.

Discuss the importance of understanding the base of logarithms when solving problems.

What should you do if your calculator does not allow you to change the base for logarithmic calculations?
