Solving Exponential Equations

The video tutorial explains how to solve an exponential equation by isolating the exponential part, converting it to a logarithmic equation, and solving for the variable x. The process involves using natural logarithms and verifying the solution through substitution and calculation. The tutorial also provides a decimal approximation of the solution and checks the accuracy using a calculator.
