The given expression is,
[tex]^5\sqrt[]{\sqrt[]{x}}[/tex]
It can be written in exponential terms as,
[tex]\begin{gathered} ^5\sqrt[]{x^{\frac{1}{2}}} \\ =(x^{\frac{1}{2}^{}})^{\frac{1}{5}} \\ =x^{\frac{1}{2}\ast\frac{1}{5}^{}}^{} \\ =x^{\frac{1}{10}} \end{gathered}[/tex]
Therefore, the simplest exponential form of the given expression is,
[tex]x^{\frac{1}{10}}[/tex]
