Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-17" was replaced by "^(-17)".

(2): "6.21" was replaced by "(621/100)".

Step  1  :

 1.1     10 = 2•5

(10)^-17 = (2•5)^(-17) = (2)^(-17) • (5)^(-17)

Equation at the end of step  1  :

  621
  ——— • ((2)(-17)•(5)(-17))
  100

Step  2  :

            621
 Simplify   ———
            100

Equation at the end of step  2  :

  621
  ——— • ((2)(-17)•(5)(-17))
  100

Step  3  :

Multiplying exponents :

 3.1    2²  multiplied by  2¹⁷   = 2^{(2 + 17)} = 2¹⁹

Multiplying exponents :

 3.2    5²  multiplied by  5¹⁷   = 5^{(2 + 17)} = 5¹⁹

Final result :

     621                                      
  ————————— = 6.21000 • 10-17 
  (219•519)
