(1): "4.2" was replaced by "(42/10)".

Step  1  :

 1.1     10 = 2•5

(10)¹² = (2•5)¹² = 2¹² • 5¹²

Equation at the end of step  1  :

  42
  —— • (212•512)
  10

Step  2  :

            21
 Simplify   ——
            5 

Equation at the end of step  2  :

  21
  —— • (212•512)
  5 

Step  3  :

Dividing exponents :

 3.1    5¹²   divided by   5¹   = 5^{(12 - 1)} = 5¹¹

Final result :

  (3•7•212•511)
