May the fourth be with you math riddle.

  78

Step-by-step explanation:

The parts of the final expression are ...

  6 walker = 150

  walker = 150/6 = 25

__

  yoda^4 = 81

  yoda = 81^(1/4) = 3

__

 2 Rtwo +100 = 120

 Rtwo = (120 -100)/2 = 10

__

  luke + yoda × Rtwo + walker × Rtwo = 285

  luke + 3×10 + 25×10 = 285

  luke = 285 -280 = 5

__

And the grand finale:

  luke ^ yoda - Rtwo(walker / luke) + yoda =

  5^3 -10(25/5) +3 = 125 -50 +3 = 78
