​

Answer 1

Answer:

${( \frac{1}{ {3}^{4} } )}^{ \frac{1}{2} } = \sqrt{ \frac{1}{ {3}^{4} } } = \frac{1}{ {3}^{2} } = \frac{1}{9}$

Answer 2

${ (\frac{1}{ {3}^{4} } )}^{ \frac{1}{2} }$

$= \sqrt{ \frac{1}{ {3}^{4} } }$

$= \sqrt { \frac{1}{81} }$

$= { \frac{1}{9} }$

$= \frac{1}{ {3}^{2} }$

$= {3}^{ - 2}$
