Question 564503
To do this problem remember that {{{sqrt(3)*sqrt(3)=3}}}

{{{sqrt(3)+6/sqrt(3)}}} we need to find a common denominator to add to a fraction.

Currently we have {{{(sqrt(3))/1+6/sqrt(3)}}} so we need to multiply the first fraction by {{{sqrt(3)/sqrt(3)}}} which will give us
{{{sqrt(3)*sqrt(3)/sqrt(3)+6/sqrt(3)}}} which would be 
{{{3/sqrt(3)+6/sqrt(3)=9/sqrt(3)}}} now generally its bad form to leave a square root on the bottom so we can multiply by  {{{sqrt(3)/sqrt(3)}}} again
{{{(9*sqrt(3))/3}}}

You can check on your calculator that what you started with and ended with have the same value (around 5.196)
