Answer:
[tex]\huge\boxed{\sf \frac{3}{\sqrt{2} }}[/tex]
Step-by-step explanation:
[tex]\displaystyle= \frac{6}{\sqrt{8} } \\\\8 \ can \ be \ written \ as \ 2 \times 2 \times 2\\\\= \frac{6}{\sqrt{2 \times 2 \times 2} } \\\\= \frac{6}{\sqrt{2^2} * \sqrt{2} } \\\\= \frac{6}{2\sqrt{2} } \\\\= \frac{3}{\sqrt{2} } \\\\\rule[225]{225}{2}[/tex]
