Question 434039
<pre>
{{{sqrt(77xy^3)/sqrt(7x)}}}

First write it all as one square root:

{{{sqrt((77xy^3)/(7x))}}}


 7 goes into 77 11 times, and the x's cancel.
So we are left with

{{{sqrt(11y^3)}}}

Write {{{y^3}}} as {{{y^2*y^1}}} or {{{y^2*y}}}

{{{sqrt(11y^2*y)}}}

Take {{{y^2}}} out in front of the radical as just {{{y}}}

{{{y*sqrt(11y)}}}
