​

Answer 1

Answer:

this is the answer

Answer 2

Answer:

Step-by-step explanation:

$x=2+\sqrt{3}$

$x+\frac{1}{x}$

$=2+\sqrt{3} +\frac{1}{2+\sqrt{3} }$

$=2+\sqrt{3} +\frac{1}{2+\sqrt{3} } \times\frac{2-\sqrt{3} }{2-\sqrt{3} }$

$=2+\sqrt{3} +\frac{2-\sqrt{3} }{4-3}$

$=2+\sqrt{3} +2-\sqrt{3}$

$=2+2$

$=4$
