Symplify (radical x/8)
is the answer x (radical 2)/4
i put it to be (x/2 radical 2)* (Radical 2/radical 2)=(x radical 2/4)

i tried it again. is it (2 radical 2x)/(8)

It depends if the expression is
√x/8 where there is no simplification, or
√(x/8)
=√x/√8
=√(x)/(2√2)
=(1/2)&radic(x/2)
or, if you wish, it could have been
=√x/(2√2)
By the way, if you would like to write √, you could simply write
& r a d i c ;
without the intervening spaces.
Do not forget to add sufficient parentheses or else it would be ambiguous.

After getting ã(x)/(2ã2)
why don't u multiply both sides by &radic(2) 
Math  nayla, Monday, November 23, 2009 at 1:38pm
after gettin &radic x/(2 &radic 2) why don't you multiply top and bottom by &radic 2

Math  nayla, Monday, November 23, 2009 at 1:52pm
ok i kind of get it

Yes, you have a point:
=√x/(2√2)
=(1/4)√(2x)
