$x \sqrt{5}$ $xsqrt5$

Explanation:

$\frac{\sqrt{45 x^{2}}}{\sqrt{9}} = \frac{\sqrt{9} \times \sqrt{5} \times \sqrt{x^{2}}}{\sqrt{9}}$ $sqrt(45x^2)/(sqrt9) = (sqrt9 xx sqrt5 xx sqrt(x^2))/(sqrt9)$
cancel $\sqrt{9}$ $sqrt9$ and
$\sqrt{x^{2}} = x$ $sqrt(x^2) = x$
answer after cancelling $\sqrt{9}$ $sqrt9$ is $x \sqrt{5}$ $xsqrt5$
