Write the simplest rationalization factor of the following surds :

$\sqrt{x^3{y}^5}$

The correct option is B $\sqrt{xy}$
$\sqrt{x^3{y}^5}$
$=\sqrt{x^2\times x\times y^4\times y}$
$=x{y}^2\sqrt{xy}$
The procedure of multiplying a surd by another surd to get a rational number is called RationalisationThe operands are called rationalizing factor (RF) of the other.
Here, $\sqrt{xy}$ is the Rationalisation Factor.
