Sweet Sixteen

Samer Adra storms onto the scene with his first sign from California.



The math works out nicely via this solution.

$$64 \div 32 = \sqrt{\sqrt{16}}$$

Samer had originally submitted this sign as a sequence sign, however, we couldn't justify it. The sequence would have been....

$$2^4, 2^5, 2^6$$

This sign is on on I-80 heading west from Reno to Sacramento
