Two students were given this problem:
x^3=-27
Emma says that the answer is -3 since she took the cube root of both sides. Alex says the answer should be "no answer" because you can't take the cube root of a negative number, the calculator says error.
Who do you agree with and why?
Emma is correct because it IS possible to take the cube root of a negative number. It isn't possible to square root a negative.
