Question

Which expression is equivalent to 4 sqrt 24x^6y/128x^4y^5

Answer 1

The first step for finding out if the expression provided is equivalent to $\sqrt{4}$ is to reduce the fraction with$x^{4}$.
$\frac{24 x^{2} y}{128 y^{5} }$
Now reduce the fraction with y.
$\frac{24 x^{2} }{128 y^{4} }$
Finally,, reduce the fraction with 8 to get your final answer.
$\frac{3 x^{2} }{16 y^{4} }$
