Logarithmic Functions and Properties

Mr. Sullivan introduces logarithmic expressions, explaining their properties and constraints. He demonstrates how to convert logarithms to exponential form and discusses common logarithms. The video also covers using calculators for logarithmic calculations and compares linear and logarithmic scales. Practice problems are provided to reinforce learning.
