Answer:

Step-by-step explanation:

1.Given : x = 7 + 4√3.

2.To find : √x + 1 / √x.

3.Solution : x = 7 + 4√3. ⇒ x = 4 + 3 + 4√3. ⇒ x = 2² + √3² + 2 × 2 × √3. ⇒ x = ( 2 + √3)² ⇒ √x = 2 + √3. Now, 1 / √x = 1 / 2 + √3 × 2 - √3 / 2 - √3. ⇒ 1 / √x = 2 - √3 / 2² - √3² ⇒ 1 / √x = 2 - √3 / 4 - 3. ⇒ 1 / √x = 2 - √3. Again, √x + 1 / √x = 2 + √3 + 2 - √3. ⇒ √x + 1 / √x = 2 + 2
