Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-5" was replaced by "^(-5)".

(2): ".899" was replaced by "(899/1000)".

Step  1  :

             899
 Simplify   ————
            1000

Equation at the end of step  1  :

            899
  (10-5) • ————
           1000

Step  2  :

 2.1     10 = 2•5

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

Equation at the end of step  2  :

                       899
  ((2)(-5)•(5)(-5)) • ————
                      1000

Step  3  :

Multiplying exponents :

 3.1    2⁵  multiplied by  2³   = 2^{(5 + 3)} = 2⁸

Multiplying exponents :

 3.2    5⁵  multiplied by  5³   = 5^{(5 + 3)} = 5⁸

Final result :

    899                                    
  ——————— = 8.99000 • 10-6
