Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-11" was replaced by "^(-11)".

(2): "1.8" was replaced by "(18/10)".

Step  1  :

 1.1     10 = 2•5

(10)^-11 = (2•5)^(-11) = (2)^(-11) • (5)^(-11)

Equation at the end of step  1  :

  18
  —— • ((2)(-11)•(5)(-11))
  10

Step  2  :

            9
 Simplify   —
            5

Equation at the end of step  2  :

  9
  — • ((2)(-11)•(5)(-11))
  5

Step  3  :

Multiplying exponents :

 3.1    5¹  multiplied by  5¹¹   = 5^{(1 + 11)} = 5¹²

Final result :

      9                                       
  ————————— = 1.80000 • 10-11
