Evaluating Logarithmic Expressions

In this video, Kumar explains how to evaluate logarithmic expressions using two examples. The first example involves finding the value of log base 4 of 32 by converting it to exponential form and solving for the exponent. The second example demonstrates evaluating log base 2 of 16 raised to the power of 1/3, again using exponential rules. The video concludes with a summary of the steps used to solve these logarithmic expressions.
