I'm a bit confused with simplifying a squared fraction. Can you explain to me how I do it?

Margaret [11]

Answer:

$\frac{\sqrt{6} }{3}$

Step-by-step explanation:

$\sqrt{\frac{2}{3} }$

$\frac{\sqrt{2} }{\sqrt{3} }$

Multiply by $\frac{\sqrt{3} }{\sqrt{3} }$ to simplify

$\frac{\sqrt{2} }{\sqrt{3} }$ * $\frac{\sqrt{3} }{\sqrt{3} }$

$\sqrt{2} *\sqrt{3} =\sqrt{6}$

$\sqrt{3} *\sqrt{3} =3$

Therefore, the final answer would be:

$\frac{\sqrt{6} }{3}$
