(1): "3.14" was replaced by "(314/100)".

Step  1  :

 1.1     42 = 2•3•7

(42)² = (2•3•7)² = 2² • 3² • 7²

Equation at the end of step  1  :

  314
  ——— • (22•32•72)
  100

Step  2  :

            157
 Simplify   ———
            50 

Equation at the end of step  2  :

  157
  ——— • (22•32•72)
  50 

Step  3  :

Dividing exponents :

 3.1    2²   divided by   2¹   = 2^{(2 - 1)} = 2¹ = 2

Final result :

  (157•2•32•72)              
  ————————————— = 5538.96000
