C. 1/2^-6 x 2^8  (2^8 = 2*2*2*2*2*2*2*2 = 256)
   1/2^-6 x 256  (when ever you do something to the power of a negative you do 1/something to the power of the number.An example is 2^-2 = 1/2^2)
so 1/2^-6 = 1/1/2^6 or 32 (message me if you want me to explain how I got that)
  32 x 256
  8,192 < answer
d. -(-2)^0 x (-2)^3 x (-2)^-4 divide (-2)^3  (anything ^0 = 1)
     -(1)   x   -8   x (-2)^-4 divide  -8    (-2^-4 = 1/-2^4)
   -1   x   -8  x  1/16  divide   -8    (simplify)
       8/16 ÷ -8
      16/8 x -8
       -16 <-- answer
e. Â I do not know the answers. Sorry
