Answer:
[tex]\frac{\sqrt{8}}{2}[/tex]
Step-by-step explanation:
[tex]\frac{4}{\sqrt{8\\}}[/tex] ; multiply first by the sqrt(8)/sqrt(8) then simplify
[tex](\frac{4}{\sqrt{8}} )(\frac{\sqrt{8}}{\sqrt{8}})\\[/tex]
= [tex]\frac{4*\sqrt{8}}{(\sqrt{8})^{2} }[/tex]
= [tex]\frac{4*\sqrt{8}}{8}[/tex]
= [tex]\frac{\sqrt{8}}{2}[/tex]
Note: this is the most simplified answer and there could be other possible answers equivalent to [tex]\frac{4}{\sqrt{8}}[/tex]
