Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-9" was replaced by "^(-9)".

(2): "2.188" was replaced by "(2188/1000)".

Step  1  :

 1.1     10 = 2•5

(10)^-9 = (2•5)^(-9) = (2)^(-9) • (5)^(-9)

Equation at the end of step  1  :

  2188
  ———— • ((2)(-9)•(5)(-9))
  1000

Step  2  :

            547
 Simplify   ———
            250

Equation at the end of step  2  :

  547
  ——— • ((2)(-9)•(5)(-9))
  250

Step  3  :

Multiplying exponents :

 3.1    2¹  multiplied by  2⁹   = 2^{(1 + 9)} = 2¹⁰

Multiplying exponents :

 3.2    5³  multiplied by  5⁹   = 5^{(3 + 9)} = 5¹²

Final result :

     547                                     
  ————————— = 2.18800 • 10-9 
  (210•512)
