Question 787079
<pre>
Simplify the expression.  Assume that all variables are positive

&#8730;x/5*&#8730;x/20

If {{{(sqrt(x)/5) * (sqrt(x)/20)}}}, then the answer is NOT 10x, as stated by the other person who responded.
{{{(sqrt(x)/5) * (sqrt(x)/20)}}} = {{{(sqrt(x) * sqrt(x))/(5 * 20)}}} = {{{sqrt(x * x)/100}}} = {{{sqrt(x^2)/100)}}} = {{{highlight(x/100)}}}</pre>
