Solve an Exponential Word Problem of Base 2

The video tutorial explains how to solve word problems involving exponential equations with base 2 using logarithms. It begins with a review of solving exponential equations and introduces a problem of doubling a stack of paper to reach the Moon. The tutorial models this problem using an exponential equation and solves it using logarithms, demonstrating that 42 doublings are needed. It also explores exponential growth through a 'pay it forward' example, showing how quickly numbers can grow. The lesson concludes by summarizing the key concepts and emphasizing the rapid nature of exponential growth.
