<PRE><B>Question 685724</B>
simplify problem below... 
(500x^4y^8)^(1/3) 
-----
Separate the problem into two pieces
where one of the pieces is the product of cubes.
----
= [(125x^3y^6)(4xy^2)]^(1/3)
-------
Rewrite as the product of 2 cube roots:
= (125x^3y^6)^(1/3) * (4xy^2)^(1/3)
------
Take the cube root of the perfect cube factor 
to get the final answer:
---
= 5xy^2*(4xy^2)^(1/3)
