Question 23242
Do you know all your perfect squares from 2^2= 4 up to 13^ = 169??  You need a perfect square that divides into 50, which would be 25.  Also, x^2 is a perfect square, so write these perfect squares in the first radical, leaving a "leftover" factor of 2 for the second radical:
{{{sqrt(50x^2) }}}
{{{sqrt(25x^2)* sqrt(2) }}}
{{{5x*sqrt(2) }}}  

You need to see my Lesson Plan on Radicals either in algebra.com or on my own website under Basic Algebra.
