These are my choices. I don't want the answer, but could you explain to me how to get the answer?

OpenStudy (solomonzelman):

\[\frac{9}{3}-\sqrt{2}\]\[3-\sqrt{2}\]

OpenStudy (solomonzelman):

I think we misunderstood the question can you retype it? here is the latex for equation-editor use. \frac{ }{ } fill in the empty spaces in brackets (in equation editor)

OpenStudy (solomonzelman):

for square rot use sqrt{ }
