The value of the variable under the radical (for now) must be greater than or equal to zero.

I'm not seeing anything in your question except: "Why do we have to be careful about variables under a radical expression? Give an example" and "so far I have for my answer :" and "Because we must isolate a radical on one side and simplify before squaring."10/22/19
