Question

If x= √5+2, then find​ x + 1/x
Pls solve step by step by photo.

Answer 1

Step-by-step explanation:

we know that,

$x = \sqrt{5 + 2}$

now , we have to find the value of X in the equation X+1/X

put the value of X in the equation X+1/X

$= \sqrt{5 + 2 } + \frac{1}{ \sqrt{5 + 2} }$

$= \sqrt{7} + \frac{1}{ \sqrt{7} }$

$= \frac{7 + 1}{ \sqrt{7} }$

$= \frac{8}{ \sqrt{7} }$
