Question

Divide then simplify by taking the roots. Assume that allexpressions under radicals represent positive numbers sqrt 324xy / 3 sqrt 3

Answer 1

bet you didn't know that
\[\sqrt{324}=18\] but it is true

Answer 2

so you get
\[\frac{18\sqrt{xy}}{3\sqrt{3}}\]
\[=\frac{6\sqrt{xy}}{\sqrt{3}}\]
\[=\frac{6\sqrt{xy}}{\sqrt{3}}\times \frac{\sqrt{3}}{\sqrt{3}}]=\frac{6\sqrt{3xy}}{3}=2\sqrt{3xy}\]

Answer 3

thanks
