Question 87949
{{{3*sqrt(486)}}}
When simplifying a problem like this, think of the factors of the expression 
under the radical. Then, you can "pull out" squares from under the radical to 
the outside. For example:
{{{486=2*3*9*9}}}
Looking at this, I immediately see that I have a 9 that can be pulled out. This 
gives me:
{{{3*9*sqrt(6)}}}
{{{highlight(27*sqrt(6))}}}
Good Luck,
