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 (x)/(22)

why don't u multiply both sides by &radic(2)

after gettin &radic x/(2 &radic 2) why don't you multiply top and bottom by &radic 2

Yes, you have a point:

=√x/(2√2)

=(1/4)√(2x)
