I like this naive approach. I know that pi(x) =~ x/log(x), roughly.
and the denominators can't force 0 = 1, since (x^2)/ln(x^2) =~
((x+1)^2)/ln((x+1)^2). It appears adequate, since we know that
there's actually quite a gap between x^2 and (x+1)^2 as the pi's
are measured; not like just saying... between x and x+2.

Good point, No idea.
