Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-7" was replaced by "^(-7)".

(2): "25.4" was replaced by "(254/10)".

Step  1  :

 1.1     10 = 2•5

(10)^-7 = (2•5)^(-7) = (2)^(-7) • (5)^(-7)

Equation at the end of step  1  :

  254
  ——— • ((2)(-7)•(5)(-7))
  10 

Step  2  :

            127
 Simplify   ———
             5 

Equation at the end of step  2  :

  127
  ——— • ((2)(-7)•(5)(-7))
   5 

Step  3  :

Multiplying exponents :

 3.1    5¹  multiplied by  5⁷   = 5^{(1 + 7)} = 5⁸

Final result :

    127                                    
  ——————— = 2.54000 • 10-6
