How do you rationalize (2sqrt(540y))/(180y)?

May 10, 2015

While $\frac{2 \sqrt{540 y}}{180 y}$ can be simplified,
it can not be completely rationalized.
As a minimum you will have $\sqrt{y}$ stuck in there somewhere.

As a simplification:
$\frac{2 \sqrt{540 y}}{180 y}$

= (2(6)sqrt(15y))/((12)(15y)

$= \frac{\sqrt{15 y}}{15 y}$
or
$= \frac{1}{\sqrt{15 y}}$
