Let : x = 5 + 2√6.

Then : x = 3 + 2 + 2√((3)(2))

=> x = (√3)² + (√2)² + 2(√3)(√2) = (√3 + √2)²

=>√x = √3 + √2 ........................................... (1)

=> 1/(√x) = 1/(√3 + √2) = √3 - √2 ....................... (2)
=> (√x) + (1/√x) = 2√3

hruthik2222: mark as brainlist if it is hlpful
JAM11: i wanted to know that why we took 3+2 as (√3)2 + (√2)2
JAM11: those 2 outside the bracket are for square
hruthik2222: yeah they ra squares
