Step-by-step explanation:
1. Rewrite 162 as
⋅2
2. factor 81 out of 162
![\sqrt{81 (2)}](https://tex.z-dn.net/?f=%5Csqrt%7B81%20%282%29%7D)
3. Rewrite 81 as ![9^{2}](https://tex.z-dn.net/?f=9%5E%7B2%7D)
![\sqrt{9^{2}.2 }](https://tex.z-dn.net/?f=%5Csqrt%7B9%5E%7B2%7D.2%20%7D)
4. Pull the terms from under the radical
![\sqrt[9]{2}](https://tex.z-dn.net/?f=%5Csqrt%5B9%5D%7B2%7D)
I hope this helps :)
