From what you wrote, we don't know if you mean 3/[2-√3] or something else. GROUPING SYMBOLS ARE NEEDED FOR CLARITY.
I'll assume that what I wrote is what you intended. Do you wish to rationalize the denominator?
If so, multiply by [2+√3]/[2+√3]. The new denominator produced by this is 1. So 3[2+√3] is the answer.
All students need to be aware of the need for proper grouping symbols when using WyzAnt's platform.
