The answer in the post by @CPhill is "The answer is -27 and 64".
This answer is incorrect.
Indeed, the number 64 is not in the list, so, there is nothing to discuss here.
Moreover, in real numbers, the given/projected equation has no solution,
since the left side of the projected equality is a negative real number,
while the right side, as the square root of a negative real number, simply is not defined in real domain.
