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): "1.475" was replaced by "(1475/1000)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  1475
  ———— • ((2)(-21)•(5)(-21))
  1000

Step  2  :

            59

Equation at the end of step  2  :

  59
  —— • ((2)(-21)•(5)(-21))
  40

Step  3  :

Multiplying exponents :

 3.1    2³  multiplied by  2²¹   = 2^{(3 + 21)} = 2²⁴

Multiplying exponents :

 3.2    5¹  multiplied by  5²¹   = 5^{(1 + 21)} = 5²²

Final result :

      59                                      
  ————————— = 1.47500 • 10-21 
  (224•522)
