Answer: The required radical form is
![\sqrt[5]{s^6}.](https://img.qammunity.org/2018/formulas/mathematics/high-school/2fxn4f01gnaa9wfqojwjefrnzx6s506fks.png)
Step-by-step explanation: We are given to write the following expression as radical :

We know that
the radicals and the fractional powers shares the following relationship :
![x^(y)/(z)=\sqrt[z]{x^y}.](https://img.qammunity.org/2018/formulas/mathematics/high-school/52kc1mxqtvl79rgabwf6qwkjhmwhn4f37z.png)
Therefore, the given expression can be written as :
![E=s^(6)/(5)=\sqrt[5]{s^6}.](https://img.qammunity.org/2018/formulas/mathematics/high-school/7dkf1e3qxxwejga8ujilwjad587lblo67q.png)
Thus, the required radical form is
![\sqrt[5]{s^6}.](https://img.qammunity.org/2018/formulas/mathematics/high-school/2fxn4f01gnaa9wfqojwjefrnzx6s506fks.png)
