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): "4.34" was replaced by "(434/100)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  434
  ——— • ((2)(-7)•(5)(-7))
  100

Step  2  :

            217
 Simplify   ———
            50 

Equation at the end of step  2  :

  217
  ——— • ((2)(-7)•(5)(-7))
  50 

Step  3  :

Multiplying exponents :

 3.1    2¹  multiplied by  2⁷   = 2^{(1 + 7)} = 2⁸

Multiplying exponents :

 3.2    5²  multiplied by  5⁷   = 5^{(2 + 7)} = 5⁹

Final result :

    217                                    
  ——————— = 4.34000 • 10-7
