Step-by-step explanation:

x = 4 + √2

then 1/x = 1/4+√2

on rationalising the denominator

(1/4+√2 ) × ( 4-√2 / 4-√2)

= 4-√2/ 4² - (√2)²

= 4-√2 / 16 - 2

= 4-√2/14

1/x = (4-√2)/14

Answer:

X=4+√2

1/X=1/4+√2

rationalising

1/4+√2×4-√2/4-√2

4-√2/4^2-√2^2

4-√2/16-2

4-√2/14=1/X

X+1/x=4+√2+4-√2/14
