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): "5.12" was replaced by "(512/100)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  512
  ——— • ((2)(-7)•(5)(-7))
  100

Step  2  :

            128
 Simplify   ———
            25 

Equation at the end of step  2  :

  128
  ——— • ((2)(-7)•(5)(-7))
  25 

Step  3  :

Multiplying exponents :

 3.1    5²  multiplied by  5⁷   = 5^{(2 + 7)} = 5⁹

Canceling Out :

 3.2      Canceling out  2⁷ as it appears on both sides of the fraction line

Final result :

   1                                  
  —— = 5.12000 • 10-7
