Understanding Logarithms

The video tutorial explains how to evaluate logarithms by converting them into exponential form. It covers various examples, including logs with different bases and exponents, and demonstrates how to solve them by hand. The tutorial also discusses the concept of negative exponents and how they relate to reciprocals, as well as the special case of logarithms with a base of 1, which always results in zero.

What is the first step in solving a logarithmic expression by hand?

• Divide by the exponent

• Convert it to a fraction

• Multiply by the base

• Set it equal to a variable
