Exponential and Logarithmic Equations and Inequalities

For most of this unit we have answered “when?” questions with tables: when does Nova pass Ridge, when does it reach 10,000, when does the caffeine drop low enough to sleep? Now we have every tool needed to solve them exactly. This note (2.13A) solves equations and inequalities where the unknown is in an EXPONENT. 2.13B solves equations with the unknown inside a LOGARITHM.
