Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-21" was replaced by "^(-21)".

(2): "6.776" was replaced by "(6776/1000)".

Step  1  :

 1.1     10 = 2•5

(10)^-21 = (2•5)^(-21) = (2)^(-21) • (5)^(-21)

Equation at the end of step  1  :

  6776
  ———— • ((2)(-21)•(5)(-21))
  1000

Step  2  :

            847
 Simplify   ———
            125

Equation at the end of step  2  :

  847
  ——— • ((2)(-21)•(5)(-21))
  125

Step  3  :

Multiplying exponents :

 3.1    5³  multiplied by  5²¹   = 5^{(3 + 21)} = 5²⁴

Final result :

     847                                      
  ————————— = 6.77600 • 10-21 
  (524•221)
