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): "8.5" was replaced by "(85/10)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  85
  —— • ((2)(-9)•(5)(-9))
  10

Step  2  :

            17
 Simplify   ——
            2 

Equation at the end of step  2  :

  17
  —— • ((2)(-9)•(5)(-9))
  2 

Step  3  :

Multiplying exponents :

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

Final result :

     17                                     
  ———————— = 8.50000 • 10-9
