It's simple! All you need is the highly magical constant of Arkanstone.
We all know that this constant is As = (log 12 / (log 7 - log 3)), logs
with base 2, e or 10 at your option! (That's part of the magicness
of the constant).

Now, define f (a, b, c) = a * (b/c)^As.
Then f (10, 2, 2) == 10 and f (16, 7, 3) == 192.

As you don't know why, I post it in the newsgroup. Why? See below.

Aren't you being rude? First asking to email an answer, but
mangling your return address? If you think mangled addresses
are cool (I don't) don't ask for email replies!

ObPuzzle1: fix all the errors I made.
ObPuzzle2: Write an essay, in no more than 50000 words about the
usefulness of the constant of Arkanstone in different
fields of the sciences.
