For this case, we must simplify the following expression:

$\sqrt [8] {x ^ 2y ^ 6}$

By properties of powers and roots we have to:

$\sqrt [n] {a ^ m}$

It can be written equivalently as:

$a ^ {\frac {m} {n}}$

Then, the previous expression can be written as:

$x ^ {\frac {2} {8}} y ^ {\frac {6} {8}}$

Simplifying we have:

$x ^ {\frac {1} {4}} y ^ {\frac {3} {4}}$

Returning to the radical form we have:

$\sqrt [4] {xy ^ 3}$

Answer:

$\sqrt [4] {xy ^ 3}$
