I'm currently taking an online college math course, and I recently came across something that I can't make any sense out of.
$(\frac{5x \cdot \sqrt{3}}{6})^2 = \frac{25x^2}{12}$
It looks like the problem is just completely throwing away the $\sqrt{3}$ instead of doing $25x \cdot 3$. Is there some condition where squaring a square root in the numerator of a fraction just gets rid of it or something? Or is it possible that this is an error with the site?
$(\frac{5x \sqrt{3}}{6})^{2}=\frac{25x^{2}\times 3}{36}$
