Answer
$2y\sqrt[5]{y}$
Work Step by Step
The given radical can be written as:
$=\sqrt[5]{2^5y^6}
\\=\sqrt[5]{(2^5y^5)y}$
RECALL:
(i) $\sqrt[n]{a^n} = |a|$ when $n$ is even
(ii) $\sqrt[n]{a^n} = a$ when $n$ is odd
The given radical has n=5, which is odd.
Use rule (ii) above to obtain:
$=2\cdot y\sqrt[5]{y}
\\=2y\sqrt[5]{y}$
