Question

Stiind ca x=radical din 3 , iar y= 1 supra rad din 3 aratati ca x pe y = 10 pe 3

Answer 1

[tex]x= \sqrt{3} \\\\ y= \frac{1}{ \sqrt{3} } \\\\ \frac{x}{y} + \frac{y}{x} = \frac{10}{3} \\\\ \frac{ \frac{1}{ \sqrt{3} } }{ \sqrt{3} } + \frac{ \frac{1}{ \sqrt{3} } }{ \sqrt{3} } = \frac{ \sqrt{3} }{1} * \frac{ \sqrt{3} }{1} + \frac{1}{ \sqrt{3} } * \frac{1}{ \sqrt{3} } \\\\ = \frac{ \sqrt{9} }{1} + \frac{1}{ \sqrt{9} } = \frac{3}{1} + \frac{1}{3} = \frac{3*3}{1*3} + \frac{1}{3} = \frac{9}{3} + \frac{1}{3} = \frac{10}{3} [/tex]
