Question

Pleaseèeeeee sent me at the moment

Answer 1

$x = \frac{ \sqrt{ \sqrt{5} + 2 } + \sqrt{ \sqrt{5} - 2 } }{ \sqrt{ \sqrt{5} + 1} } \\ {x}^{2} = \frac{ \sqrt{5} + 2 + \sqrt{5} - 2 + 2 \sqrt{3} }{ \sqrt{5} - 1 } \\ {x}^{2} = \frac{2 \sqrt{ 5 } + 2 \sqrt{3} }{ \sqrt{5 } - 1} \\ {x}^{2} = 2\frac{ \sqrt{5} + \sqrt{3} }{ \sqrt{5} - 1 }$
