Double Square



Another mathematically significant roadsign from rural New York found by previous winner David Slauenwhite. Harpursville is too small to leave much of a trace on the Internet but the city of Binghamton is a good sized college town with around 47,000 people. Binghamton is known as the "carousel capital of the world" with six working carousels in the region. It is also home to the fifth-oldest zoo in the nation, which given the history of zoos is likely something to have mixed feelings about.

This sign takes square roots to a new place for road sign math! Nowhere in the rules is there are requirement that intermediate calculations must result in a number that is on the sign, as such, this is a winner by using a double squrare root. It would be pretty amazing to find a sign that took this to one more square root.

$$\sqrt{\sqrt {16} } = 2 $$

This sign is on Route 7 where it intersects with Route 79. If you wish to visit this sign it is easily seen by taking Exit 8 off of I-88, the exit for Harpursville, New York.
