Question 55857
{{{ 2x(sqrt(2x))(3sqrt(5x)) }}}
First multiply what is OUTSIDE the roots
{{{ 6x(sqrt(2x))(sqrt(5x)) }}}
Multiply what is INSIDE the roots
{{{ 6x(sqrt(10x^2)) }}}
the root cancels the x^2, and so it comes to the outside
{{{ 6x*x*(sqrt(10)) }}}
Combine the x terms
{{{ 6x^2(sqrt(10)) }}}
