The given expression is:

$\sqrt[4]{ 9^{ (1)/(2)x } }$

4th root is equivalent to raising the expression to power
(1)/(4)

. So, re-writing the expression by converting radical to exponent:

$( 9^{ (1)/(2)x } )^{ (1)/(4) } \\ \\ = 9^{ (1)/(8)x }$

Therefore, the given expression simplifies to
$9^{ (1)/(8)x }$
