Learn how to solve logarithmic equations using the 'antilog' concept, including looking at restrictions on variables in expressions involved, and several equations that result in extraneous solutions.
See the rest of my videos covering other Exponential and Logarithmic Expressions and Equations concepts:    • ★ Exponential & Logarithmic Expressio...  

Corresponds to chapter 8, section 8.4 in McGraw-Hill's Pre-Calculus 12, but also fits with the exponents and logarithms unit from almost any other Pre-Calculus course or textbook.

My instructional approach emphasizes conceptual understanding of and connections between concepts and ideas, rather than just pure memorization.
