(1): "7.2" was replaced by "(72/10)".

Step  1  :

 1.1     10 = 2•5

(10)²¹ = (2•5)²¹ = 2²¹ • 5²¹

Equation at the end of step  1  :

  72
  —— • (221•521)
  10

Step  2  :

            36
 Simplify   ——
            5 

Equation at the end of step  2  :

  36
  —— • (221•521)
  5 

Step  3  :

Multiplying exponents :

 3.1    2²  multiplied by  2²¹   = 2^{(2 + 21)} = 2²³

Dividing exponents :

 3.2    5²¹   divided by   5¹   = 5^{(21 - 1)} = 5²⁰

Final result :

  (223•32•520)
