Answer 2

Answer:

Step-by-step explanation:

x + 1/x= 7+4root3 +1  / 7+ 4 root 3

= (7+ $4\sqrt{3\\}$) + 1/7+4root3 *  4 - root3/4 - root3

=( 7+ $4\sqrt{3\\}$) + 7-4root3/ $7^{2}$ -  $4\sqrt{3} ^{2}$

= (7+ $4\sqrt{3\\}$ ) + (7- $4\sqrt{3\\}$ ) / 49 - 48

=  (7+ $4\sqrt{3\\}$ ) +  (7- $4\sqrt{3\\}$ )

=  7+ $4\sqrt{3\\}$ + 7- $4\sqrt{3\\}$

= 7 + 7
