Question 92055
You cannot simplify any further because these are two different terms.  Their radicands are different.

.
If the problem was:
{{{3sqrt(2)-2sqrt(2))}}} than you could combine the like terms (subtract), because the radicands are the same ({{{(sqrt(2))}}}).
{{{3sqrt(2)-2sqrt(2))}}}
{{{1sqrt(2)))}}}
