Question 83444
<pre>
perform the indicated division.  rationalize the denominator if necessary then simplify each radical expression

-9-square root of 108
over
3

               {{{(- 9 - sqrt(108))/3}}} 
               {{{(- 9 - sqrt(36 * 3))/3}}} = {{{(- 9 - sqrt(36)*sqrt(3))/3}}} = {{{(- 9 - 6sqrt(3))/3}}} = {{{3(- 3 - 2sqrt(3))/3}}} = {{{cross(3)(- 3 - 2sqrt(3))/cross(3)}}} = {{{highlight(- 3 - 2sqrt(3)))}}} <==== Correct answer!

That is, if it's NOT {{{- 9 - sqrt(108)/3}}}</pre>
