The given expression is:

$\sqrt[4]{ 9^{ \frac{1}{2}x } }$

4th root is equivalent to raising the expression to power $\frac{1}{4}$ . So, re-writing the expression by converting radical to exponent:

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

Therefore, the given expression simplifies to $9^{ \frac{1}{8}x }$
