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

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  1765 • ((2)(-18)•(5)(-18))

Step  2  :

Dividing exponents :

 2.1    5¹   divided by   5¹⁸   = 5^{(1 - 18)} = 5^(-17) = ¹/_5¹⁷

Final result :

     353                                      
  ————————— = 1.76500 • 10-15 
  (218•517)
