24.3.6 Simplifying and Evaluating with Log Rules

Core idea

Break a tangle of multiplications and divisions into added and subtracted logs, and a few steps crack a number that was hard to compute.

Module goal. Introduce logarithms as the inverse of exponentiation, master the idea and its operation rules, the central hub of this stage
