(1): "1.25" was replaced by "(125/100)".

Step  1  :

 1.1     10 = 2•5

(10)¹⁸ = (2•5)¹⁸ = 2¹⁸ • 5¹⁸

Equation at the end of step  1  :

  125
  ——— • (218•518))
  100

Step  2  :

            5
 Simplify   —
            4

Equation at the end of step  2  :

  5
  — • (218•518))
  4

Step  3  :

Multiplying exponents :

 3.1    5¹  multiplied by  5¹⁸   = 5^{(1 + 18)} = 5¹⁹

Dividing exponents :

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

Equation at the end of step  3  :

Step  4  :

                1    
 Simplify   —————————
            (519•216) 

Final result :

      1                                       
  ————————— = 8.00000 • 10-19 
  (519•216)
