BARS::Muralized Road Sign in Pacific Beach, California

This road sign is painted into a mural found in Pacific Beach, California.

The muralized road sign says...

   +------------------------+
   | La Jolla             4 |
   | Los Angeles        123 |
   | Mission Beach        1 |
   | Ocean Beach      3 1/2 |
   | San Diego           10 |
   +------------------------+
   the numbers are:  4  123  1  3.5  10

   the math is:  sqrt(123 - sqrt(4)) - 10 = 1^(3.5)

   rsAgeEval:  (4^3.5 - 123) * 10 + 1 = 51
   * RoadHacker was 51 years young when he found this mural.

   rs42Eval:  123 / floor(3.5) + sqrt(4) - (1 - log(10))! = 42
   * 42 is the "Answer to Life, the Universe, and Everything"

   more math:  log(sqrt(123 - sqrt(4) * 10 - floor(3.5))) = 1

   more math:  123 - 10^sqrt(4) + 1 = ceil(3.5)!

   more math:  (4 * 10 + 1) * floor(3.5) = 123

   more math:  sqrt(123 - reciprocal(4 - 3 1/2)) - 1 = 10

Exercises
  1. Solve for n:    123 - 10^sqrt(4) + n = 24

  2. Solve for n:    (n * 10 + 1) * 3 = 123

  3. Solve for n:    (4^n - 123) * 10 + 1 = 51

  4. Solve for n:    log(sqrt(123 - 4^(1/2) * n - 3)) = 1
    hint: sqrt(n) = n^(1/2)

  5. The number 123 is semiprime (or biprime) because it has only two prime factors and they are _____ and _____.
