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): "0.45" was replaced by "(45/100)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

   45
  ——— • ((2)(-9)•(5)(-9))
  100

Step  2  :

             9
 Simplify   ——
            20

Equation at the end of step  2  :

   9
  —— • ((2)(-9)•(5)(-9))
  20

Step  3  :

Multiplying exponents :

 3.1    2²  multiplied by  2⁹   = 2^{(2 + 9)} = 2¹¹

Multiplying exponents :

 3.2    5¹  multiplied by  5⁹   = 5^{(1 + 9)} = 5¹⁰

Final result :

      9                                       
  ————————— = 4.50000 • 10-10 
  (211•510)
