Question 174534
Is this your problem?  {{{sqrt(5xy^7)*sqrt(10x^3y^3) }}}???

If so, multiply the radicands (inside the square roots!) together to get
{{{sqrt(50x^4y^10) }}}


Sort out the perfect squares by forming two square roots:
{{{sqrt(25x^4y^10)*sqrt(2) }}}


Simplify the square root that is a perfect square:
{{{ 5x^2*y^5 *sqrt(2) }}}


If you need resources and explanations that PLATO does NOT provide, then you need to see my website!!  Click on my tutor name, "rapaljer" anywhere in algebra.com, and then take my first main link on my homepage which is "Basic, Intermediate, and College Algebra: One Step at a Time."  Go to Basic Algebra, Chapter 5, and you will find the ENTIRE chapter on Square Roots, complete with explanations, examples, exercises, and answers in a Discovery Method format, a LOT easier to understand than PLATO, and UNLIKE PLATO, IT's ALL FREE!!!!
