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

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  8 • ((2)(-11)•(5)(-11))

Step  2  :

Dividing exponents :

 2.1    2³   divided by   2¹¹   = 2^{(3 - 11)} = 2^(-8) = ¹/_2⁸

Final result :

      1                                      
  ———————— = 8.00000 • 10-11 
  (28•511)
