​

Answer 1

Answer:

4

Step-by-step explanation:

Given : x = 2 + √3

To Find : find the value of x + 1/x

Solution:

x + 1/x

Since x = 2 + √3

To find 1/x

x = 2 + √3

1/x = 1/2+√3 x  2-√3/2-√3

1/x = 2-√3/(2)2 - (√3)2

1/x = 2-√3/4-3

1/x = 2-√3

Substitute the values

x + 1/x

2 + √3 + 2- √3

4

Hence the value of x+1/x is 4
