(1): "1.05" was replaced by "(105/100)".

Step  1  :

            21
 Simplify   ——
            20

Equation at the end of step  1  :

  21
 (——)30
  20

Step  2  :

 2.1     21 = 3•7

(21)³⁰ = (3•7)³⁰ = 3³⁰ • 7³⁰  2.2     20 = 2²•5 (20)³⁰ = (2²•5)³⁰ = 2⁶⁰ • 5³⁰

Final result :

  (330•730)           
  ————————— = 4.32194 
  (260•530)
