BARS::27 Miles From Why and 81 Miles From Gila Bend in Arizona

This road sign is on northbound AZ Hwy-85 in Arizona.

```   +-----------------+
| Why          27 |
| Gila Bend    81 |
+-----------------+
```
```   the numbers are:  27  81

the math is:  cuberoot(27) = sqrt(sqrt(81))

more math:  cuberoot(27) = 4root(81)

rs42Eval:  summation(cuberoot(27), sqrt(81)) = 42
* 42 is the "Answer to Life, the Universe, and Everything"
* summation(3, 9) = 3+4+5+6+7+8+9 = 42

rsAgeEval:  cuberoot(27)! * sqrt(81) = 54
* RoadHacker was 54 years young when he found this road sign.

rsAgeEval:  avg(27, 81) = 54
* RoadHacker was 54 years young when he found this road sign.

rsCardinalityEval:  cuberoot(27)! / sqrt(81) = 2
* There are two numbers in this road sign.

* spf(27) = 3+3+3 = 9; spf(81) = 3+3+3+3 = 12
* spf(n) = the sum of the prime factors of n

BARSfunc math:  spf(27) = sqrt(81)

BARSfunc rsCardinalityEval:  spf(81) / cuberoot(27)! = 2
* There are two numbers in this road sign.

off-by-one rsHwyEval:  81 + cuberoot(27) = 85-1
* This road sign is on AZ Hwy-85.
