I’m doing something that I should have done a long time ago: collecting a series of posts into one single post. The following links comprised my series on the decimal expansions of logarithms.
Part 1: Pedagogical motivation: how can students develop a better understanding for the apparently random jumble of digits in irrational logarithms?
Part 2: Idea: use large powers.
Part 3: Further idea: use very large powers.
Part 4: Connect to continued fractions and convergents.
Part 5: Tips for students to find these very large powers.
