Question

Please brake down why!

Answer 1

Answer:

A

Step-by-step explanation:

$\frac{\sqrt{54}.\sqrt{2} } {\sqrt{3.2}} = \frac{\sqrt{54}.\sqrt{2} } {\sqrt{3}.\sqrt{2}}= \frac{\sqrt{54} } {\sqrt{3}} = \frac{\sqrt{18.3}} {\sqrt{3}}= \frac{\sqrt{18}.\sqrt{3} } {\sqrt{3}} =\sqrt{18} = \sqrt{3.3.2} = 3\sqrt{2}$
