Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-8" was replaced by "^(-8)".

(2): "1.72" was replaced by "(172/100)".

Step  1  :

 1.1     10 = 2•5

(10)^-8 = (2•5)^(-8) = (2)^(-8) • (5)^(-8)

Equation at the end of step  1  :

  172
  ——— • ((2)(-8)•(5)(-8))
  100

Step  2  :

            43
 Simplify   ——
            25

Equation at the end of step  2  :

  43
  —— • ((2)(-8)•(5)(-8))
  25

Step  3  :

Multiplying exponents :

 3.1    5²  multiplied by  5⁸   = 5^{(2 + 8)} = 5¹⁰

Final result :

     43                                     
  ———————— = 1.72000 • 10-8
