BARS::Nearing Wahiawa on the Hawaiian Island of Oahu

This road sign is on the Hawaiian Island of Oahu.

Note: This road sign was discovered by SCC student Lindsay during the fall 2008 semester and the dot-jpg was given to MathBabbler on 7 October 2008.

The road sign says...

   +---------------------------+
   | Mililani Tech Park    1/2 |
   | Wheeler AAF           1/2 |
   | Wahiawa                 2 |
   +---------------------------+
   the numbers are:  1/2  1/2  2

   fooish (trivial) math:  sqrt((1/2)^2) = 1/2

   more fooish math:  sqrt(reciprocal(2 / 1/2)) = 1/2
   
   observe...
      2 / 1/2 = 4
      reciprocal(4) = 1/4
      sqrt(1/4) = sqrt(1)/sqrt(4) = 1/2

   more fooish math:  sqrt(reciprocal(1/2 * 1/2)) = 2

   observe...
      1/2 * 1/2 = 1/4
      reciprocal(1/4) = 4
      sqrt(4) = 2

   [solve for 'n']  ((1/2)^n)^(1/2) = 1/2
