The other person wrote, "Now, you need to see that {{{75=5*4*4}}}, so you can also pull out a 4 from under the radical"
How does this make sense? In what universe is {{{75=5*4*4}}}? As a result, his answer, {{{4a}}} is obviosly WRONG!!

{{{highlight(sqrt(75a^2)/sqrt(5))}}} = {{{sqrt(75a^2/5)}}} = {{{sqrt(15a^2)}}} = {{{highlight(matrix(1,4, a*sqrt(15),",", or, sqrt(15)a))}}}</font></font></font></b></pre>
