Răspuns:
[tex]\frac{x}{y} +\frac{y}{x} =2[/tex]
Explicație pas cu pas:
[tex]x=\sqrt{3} , y=\frac{1}{\sqrt{3} } \\\frac{x}{y}=\frac{\sqrt{3} }{\frac{1}{\sqrt{3} } }=\frac{\sqrt{3} }{1} × \frac{1}{\sqrt{3} }[/tex]. [tex]\sqrt{3}[/tex] se simplifica si rezulta ca x/y=1
y/x= [tex]\frac{y}{x}= \frac{\frac{1}{\sqrt{3} } }{\sqrt{3} }= \frac{1}{\sqrt{3} }\frac{\sqrt{3} }{1} =1[/tex] x/y+y/x=2
