Evaluate a Natural Logarithm Without a Calculator

The video tutorial explains how to evaluate a logarithmic expression without using a calculator. It begins by discussing the base of natural logarithms, emphasizing that the base is often implied to be E. The instructor then demonstrates how to rewrite fractions using negative exponents. Following this, the properties of logarithms are applied to simplify the expression. Finally, the solution is evaluated, showing that the expression simplifies to -6.
