Exponential Population Growth Concepts

The video tutorial by Mark Kedos on MathGuide.com covers the topic of population growth, explaining its mathematical representation and solving two example problems. The first problem involves predicting future population using a given growth rate, while the second problem uses logarithms to calculate the time required for a population to reach a certain size. The video concludes with a discussion on global population trends and the importance of family planning.
