Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-10" was replaced by "^(-10)".

(2): ".67" was replaced by "(67/100)".

Step  1  :

             67
 Simplify   ———
            100

Equation at the end of step  1  :

             67
  (10-10) • ———
            100

Step  2  :

 2.1     10 = 2•5

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

Equation at the end of step  2  :

                         67
  ((2)(-10)•(5)(-10)) • ———
                        100

Step  3  :

Multiplying exponents :

 3.1    2¹⁰  multiplied by  2²   = 2^{(10 + 2)} = 2¹²

Multiplying exponents :

 3.2    5¹⁰  multiplied by  5²   = 5^{(10 + 2)} = 5¹²

Final result :

      67                                      
  ————————— = 6.70000 • 10-11 
  (212•512)
