d) Not a real number
:
The way you have it written the answer would be -24, but since this is not a choice, I think that perhaps it's suppose to be
- third root of 64 (with the three as an index to the radical)
In that case
=- third root of (4*4*4)
=-third root of (4^3)
=-4
which is a.
Happy Calculating!!!
