(1): "^-5" was replaced by "^(-5)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  268 • ((2)(-5)•(5)(-5))

Step  2  :

Dividing exponents :

 2.1    2²   divided by   2⁵   = 2^{(2 - 5)} = 2^(-3) = ¹/_2³

Final result :

     67             
  ——————— = 0.00268 
  (23•55)
