Simple.....

[tex] x^{4} [/tex]

All you have to do is simplify the radical by breaking the radicand up into a product of known factors.

Thus, your answer.
It would be [tex]x^4[/tex]

I'm not sure what method you use to do these problems, but if you ever have one like this, it's essentially dividing by 2 for the exponent only. 8/2 is 4, so it's 
 [tex]x^4[/tex]
