Great teaching! Whoever though of logarithms was a true pragmatic genius. Thinking of powers rather than actual numbers could make many applications feasible. Graphing actual numbers could sometimes be a nightmare, but when substituting numbers by powers of bases like 10 or e could make the graph fit on a page otherwise in need of a very huge surface. Because logarithms are the inverse functions of the exponential functions and because of the Euler’s formula and identity, trigonometric functions and exponential functions strike a fascinating relationship.

Do you offer any educational material for the Math portion of the wonderlic exam?

I got the two answers OK, but failed to flag the positive number as the only true solution. You got me!

6:59 for such a VERY verbose video you should have provided that "condensing" formula - usually you do, what happened this time ?
This is one of those very few videos where you didn't explain well.
Just keeping blabbing "you should be able to condense/expand" without actually providing the formula to do it with: log(a) + log(b) = log(a*b)
