Logarithms in ANY Base (Base-a) • [8.1b] PRE-CALCULUS 12

Learn how the concept of logarithms can be extended beyond base-10 to ANY base, including how to determine and estimate logarithms in any base, and what the ‘logBASE’ or equivalent key on your calculator does.

Corresponds to chapter 8, section 8.1 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.
