(1): "^-3" was replaced by "^(-3)".

Step  1  :

 1.1     26 = 2•13

(26)^-3 = (2•13)^(-3) = (2)^(-3) • (13)^(-3)

Equation at the end of step  1  :

  (128 • ((2)(-3)•(13)(-3))) • -2

Step  2  :

Dividing exponents :

 2.1    2⁷   divided by   2³   = 2^{(7 - 3)} = 2⁴

Equation at the end of step  2  :

   16 
  ———— • -2

Step  3  :

Final result :

   -32            
  ———— = -0.01457
