1 : Simplify the following type one radical. Notice that the root symbol is
already supplied for you so you only need to supply the inside and outside functions
(no need to expand them!)
If the radicand completely simplifies out of the radical,
enter for the radicand in your answer. If the radicand can’t be simplified out at all,
enter in as the radical coefficient.
Unfortunately the validator isn’t smart enough to know if a negative should be inside
or outside the radical (yet). I’m working on improving the validation technique, but
for now if you think the answer is correct but it isn’t being accepted, try the negative
of your answer.
