Enter the answer in the following format: If the answer is +27\\3, enter +- 2i for outside of radical and 3 for under the radical. If the answer is 2i (since it equals 27\\1 ), enter 2i for outside of radical and 1 for under the radical. If the answer is -2V3, enter -2 for outside of radical and 3 for under the radical.
