Answer:
a: exact
Step-by-step explanation:
if youre adding, giving an estimate is just giving a wrong answer unless you put the squiggly equal sign, or the teacher asks for an estimate
The answer would be yes because if you take a negative number say, -10 and take it to the power of 3 (cub(e)(ing)) -10^3 you have to take -10* itself 3 times and when you do that the first time that you do that you get this -10*-10=100 but them you still have to times it by -10 one more time because its a cube((-e)ing) meaning 3 so we take it times -10 once more and we get are end answer of 100*-10=-1000.
So to answer your question yes it is possible in a cubing now if this was a squaring then no because a negaive time a negative is always a positive.
