The first step for finding out if the expression provided is equivalent to
![√(4)](https://img.qammunity.org/2019/formulas/mathematics/high-school/uxynyzfp7sf7nt8qy9qwgmpdwakpr63to0.png)
is to reduce the fraction with
![x^(4)](https://img.qammunity.org/2019/formulas/mathematics/high-school/xc5rtotxegpuboutdosy7pyo6wtdhqsqpg.png)
.
![(24 x^(2) y)/(128 y^(5) )](https://img.qammunity.org/2019/formulas/mathematics/high-school/hdrtgbieg3t780t13hdgzo22mpiqphvcv8.png)
Now reduce the fraction with y.
![(24 x^(2) )/(128 y^(4) )](https://img.qammunity.org/2019/formulas/mathematics/high-school/v3j06hqwvnmvm7hmc95kf47ghnkkhoc97c.png)
Finally,, reduce the fraction with 8 to get your final answer.
![(3 x^(2) )/(16 y^(4) )](https://img.qammunity.org/2019/formulas/mathematics/high-school/ghps6yew0xuokhdrnxdx93dv4w3df6plt3.png)
