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): "1.8" was replaced by "(18/10)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  18
  —— • ((2)(-7)•(5)(-7))
  10

Step  2  :

            9
 Simplify   —
            5

Equation at the end of step  2  :

  9
  — • ((2)(-7)•(5)(-7))
  5

Step  3  :

Multiplying exponents :

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

Final result :

     9                                     
  ——————— = 1.80000 • 10-7 
  (58•27)
