Question 568362
<pre>

Assuming x and y are non-negative:

{{{root(4,80x^5y^3)}}}

{{{root(4,2*2*2*2*5*x*x*x*x*x*y*y*y)}}}

{{{root(4,(2*2*2*2)*5*(x*x*x*x)*x*(y*y*y))}}}

{{{root(4,2^4*5*x^4*x*y^3)}}}

{{{root(4,2^4*x^4*5*x*y^3)}}}


{{{root(4,2^4)*root(4,x^4)root(4,5*x*y^3)}}}

2x{{{root(4,5xy^3)}}}
