Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-15" was replaced by "^(-15)".

(2): "1.691" was replaced by "(1691/1000)".

Step  1  :

 1.1     10 = 2•5

(10)^-15 = (2•5)^(-15) = (2)^(-15) • (5)^(-15)

Equation at the end of step  1  :

  1691
  ———— • ((2)(-15)•(5)(-15))
  1000

Step  2  :

            1691
 Simplify   ————
            1000

Equation at the end of step  2  :

  1691
  ———— • ((2)(-15)•(5)(-15))
  1000

Step  3  :

Multiplying exponents :

 3.1    2³  multiplied by  2¹⁵   = 2^{(3 + 15)} = 2¹⁸

Multiplying exponents :

 3.2    5³  multiplied by  5¹⁵   = 5^{(3 + 15)} = 5¹⁸

Final result :

     1691                                     
  ————————— = 1.69100 • 10-15 
  (218•518)
