Question

x=7-4√3 then x+1/x find the valve<br />​

Answer 1

Step-by-step explanation:

Here,

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

$\frac{7 - 4 \sqrt{3} + 1 }{7 -4 \sqrt{3} } \times \frac{7 + 4 \sqrt{3} }{7 + 4 \sqrt{3} }$

$\frac{49 - 48 + 7 + 4 \sqrt{3} }{49 - 48}$

$8 + 4 \sqrt{3}$

or

$4(2 + \sqrt{3} )$

Its your answer

Answer 2

Answer:

hey mate here's ur answer.

x =7 - 4√3

then

1/x = 1/ 7 -4√3

(now by rationalising this)

7 + 4√3 / (7)^2 -(4√3)^2

7 + 4√3 / 49 - 48

7+ 4√3 /1

7 +4√3.

now,

x+1/x

7 -4√3 + 7 + 4√3

7 +7

14.

so 14 is the answer.

hope this helps you ♥️♥️
