The video tutorial explains how to solve a mathematical problem involving exponents and logarithms. It begins by discussing the need to isolate the exponent and then demonstrates dividing both sides of the equation to achieve this. The tutorial then introduces the use of logarithms, specifically base 10, to further simplify the equation. The instructor provides clarifications on the assumptions made about base 10 and concludes with the final steps to solve the problem.
