Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-18" was replaced by "^(-18)".

(2): "3.5" was replaced by "(35/10)".

Step  1  :

 1.1     10 = 2•5

(10)^-18 = (2•5)^(-18) = (2)^(-18) • (5)^(-18)

Equation at the end of step  1  :

  35
  —— • ((2)(-18)•(5)(-18))
  10

Step  2  :

            7
 Simplify   —
            2

Equation at the end of step  2  :

  7
  — • ((2)(-18)•(5)(-18))
  2

Step  3  :

Multiplying exponents :

 3.1    2¹  multiplied by  2¹⁸   = 2^{(1 + 18)} = 2¹⁹

Final result :

      7                                       
  ————————— = 3.50000 • 10-18 
  (219•518)
