(1): "6.25" was replaced by "(625/100)".

Step  1  :

 1.1     10 = 2•5

(10)¹⁸ = (2•5)¹⁸ = 2¹⁸ • 5¹⁸

Equation at the end of step  1  :

  625
  ——— • (218•518))
  100

Step  2  :

            25
 Simplify   ——
            4 

Equation at the end of step  2  :

  25
  —— • (218•518))
  (4

Step  3  :

Multiplying exponents :

 3.1    5²  multiplied by  5¹⁸   = 5^{(2 + 18)} = 5²⁰

Dividing exponents :

 3.2    2¹⁸   divided by   2²   = 2^{(18 - 2)} = 2¹⁶

Equation at the end of step  3  :

Step  4  :

                1    
 Simplify   —————————
            (520•216) 

Final result :

      1                                       
  ————————— = 1.60000 • 10-19 
  (520•216)
