The video introduces logarithms by defining them and explaining their relationship with exponentials. It uses examples to illustrate exponentials and their growth analogy. The teacher explains index laws and how they relate to growth and time. The video then transitions to converting exponentials into logarithmic form and solving logarithmic equations with examples, including changing the base.

What is a logarithm primarily described as in relation to exponentials?

• A complex form of multiplication

• A different perspective on exponentials

• A simpler form of addition

• A method to divide numbers
