Answer
$\sqrt (3x)/8$
Work Step by Step
We can simplify the expression as follows:
= $\sqrt (3x^{3} / 64x^{2})$
= $\sqrt 3\sqrt x^{2}\sqrt x / \sqrt 64\sqrt x^{2}$
$ \sqrt xy =\sqrt x * \sqrt y$)
= $x\sqrt 3\sqrt x / 8x$
= $\sqrt (3x) / 8$. (Using the multiplication theorem, $\sqrt x * \sqrt y= \sqrt xy$)
