Question

if x=5-2√6, find the value of√x+2/√x​

Answer 1

Solution:-

x = 5 - 2√6

1/x = {1/(5 - 2√6)

⇒ 1/x = {1/(5 - 2√6)} × (5 + 2√6)/(5 + 2√6)

= (5 + 2√6)/25 - 24

= 5 + 2√6

Now,

(√x + 1/√x²) = x + 1/x + 2 × √x × 1/√x

= x + 1/x + 2

⇒ √x + 1/√x = √x + 1/x + 2 (whole root)

= √5 - 2√6 + 5 + 2√6 + 2

= √5 + 5 + 2

= √12
