Answer:
1st, 2nd, and last.
Explanation:
For the first two common rules can be applied such as 
 =
 = 
![\frac{\sqrt[n]{a} }{\sqrt[n]{b} }](https://img.qammunity.org/2020/formulas/mathematics/middle-school/zwwquc9ezfku4kh45up6v1spyfkj1dsbnz.png) and that
 and that 
![\sqrt[n]{(a)/(b) } = ((a)/(b))^(n)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/can0mozrxy5wfcluh6axlsrgpix8qi6c0j.png) 
 
and for the last one this is just simplifying the radical and if you factor it you realize that, 
 meaning that you can take the radical off of 5/8 and end up with that final answer
