For this case, we must simplify the following expression:
![\sqrt [8] {x ^ 2y ^ 6}](https://img.qammunity.org/2020/formulas/mathematics/high-school/f931jngblustek5qaflvb4e6kxhkx4unyp.png)
By properties of powers and roots we have to:
![\sqrt [n] {a ^ m}](https://img.qammunity.org/2020/formulas/mathematics/high-school/wbjlx0yk7pbhua5frqzq59tr1gykkniyo1.png)
It can be written equivalently as:
![a ^ {\frac {m} {n}}](https://img.qammunity.org/2020/formulas/mathematics/high-school/6i2okijui4gnlu6bniq3h6kil2wxuxbnm6.png)
Then, the previous expression can be written as:
![x ^ {\frac {2} {8}} y ^ {\frac {6} {8}}](https://img.qammunity.org/2020/formulas/mathematics/high-school/5a7e7c1q4abo7o8r1bxpm7d33ly8acytu2.png)
Simplifying we have:
![x ^ {\frac {1} {4}} y ^ {\frac {3} {4}}](https://img.qammunity.org/2020/formulas/mathematics/high-school/70cgcpmf4ntkd7xu5aqy985nw6iv773br9.png)
Returning to the radical form we have:
![\sqrt [4] {xy ^ 3}](https://img.qammunity.org/2020/formulas/mathematics/high-school/agd0o8t7j7uxryqwffiwtsxqig4eysipdq.png)
Answer:
![\sqrt [4] {xy ^ 3}](https://img.qammunity.org/2020/formulas/mathematics/high-school/agd0o8t7j7uxryqwffiwtsxqig4eysipdq.png)
