Question 542395
{{{ sqrt(4/x) }}}
-----------
{{{ sqrt(4) / sqrt(x) }}}
-----------
{{{ 2 / sqrt(x) }}}
-----------
Multiply top and bottom by {{{ sqrt(x) / sqrt(x) }}}
{{{ ( 2/sqrt(x) )*( sqrt(x) / sqrt(x)) }}}
-----------
{{{ ( 2*sqrt(x) ) / x }}}
I did this last step because square roots on top
of a fraction are usually preferred over
square roots on the bottom
