Yes, you can. For example, the cube root of (-8) is (-2), because
(-2)*(-2)*(-2) = -8.

Yes, because you can multiply 3 same (negative) numbers to get a negative number, therefore, it is possible to take a cube root of negative numbers. But with a square root, you can't because you cannot multiply two same numbers to get a negative answer. Hope this helps ^ _ ^

Yes you can have the Nth root of a negative number.
if N is even like 2, i.e. square root. the result is in form of a imaginary number "i" as sqrt(-1) =1
but if N is a odd number, like 3, i.e. cube root the result is a negative number as (-1)^(1/3) = -1
for any negative number, -x factor it as: (-1)*x
and that'll help you in the understanding

Yes you can. the cube root of -27 is -3. Check that with your calculator if you don't believe me.

yes u can.
eg: -2 * -2 * -2 = -8
i.e. cube root of -8 is -2. always the cube root of -ve number is -ve.
in maths when u multiply 2 -ve numbers u get a +ve ans. when u do multiply 3 -ve numbers u get a -ve ans.

Yes, cubes are possible. Squares however result in imaginary numbers.
