Please give me answer please please please

Answer 1

Answer:

Now

x

1

=5+2

6

Thus the value of (x−

x

1

)

2

=((5 - 2

6

) - (5 + 2

6

))

2

=(4\sqrt{6})^2= 16×6 = 96

Thus the correct answer is 96.

Answer 2

Answer:

If x=5-2root6

Then 1/x=

$\frac{1}{5 - 2 \sqrt{6} } \times \frac{5 + 2 \sqrt{6} }{5 + 2 \sqrt{6} }$

= 5+2 root 6

Now x+1/x= 5-2 root 6 + 5+2 root 6

= 5+5 =10

Therefore, the ans is 10
