Tutorial - Evaluating Logarithms Without a Calculator

The video tutorial explains how to solve a mathematical problem involving exponentiation. It begins by posing the question of what power 4 must be raised to in order to equal 64. The instructor suggests a methodical approach by calculating successive powers of 4 until reaching the answer. The solution is found when 4 raised to the third power equals 64. The tutorial concludes by summarizing the process and confirming the answer, demonstrating how to evaluate a logarithmic expression.
