Properties of log:

Log (base a) b = [log (base 10) b] / [log (base 10) a]

The above formula works for any base, as long as numerator and denominator are both logs of the same base..

So Log (base 6) 37.9 = [log (base 10) 37.9] /[ log (base 10) 6].

log[base 6](37.9)

Use the change of base formula, to *make* it log base 10. The change of base formula goes as follows:

log[base c](a) = log[base b](a) / log[base b](c)
where you can choose your own base b.

Therefore, you can go

log(37.9) / log(6)

or, you can choose base e, and have

ln(37.9) / ln(6)

Both should give you the same result.

The first thing that you need to do is find a beaver. If the beaver isn't wet - then find a way to make it wet.

Since we all know that Tony George likes cocaine - we can assume that he free bases it. That is your base.

Take the IRL average ratings (0.1) and figure in danicova's bra size (another 0.1)

you get you answer of WGAF.
