Question

if X=2+ root3,then(X+1/X)equals to​

Answer 1

Answer:

if X equal to 2 + root 3 then find value of 1 upon 2 + root 3 implies that 2 minus root 3 upon now 2 Plus root 3 plus two 2 - root 3 is equal to 4

Answer 2

x = 2+√3

1/x = 1/2+√3

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

1/x = 2-√3/4-3

1/X= 2-√3/1

THEREFORE, (X+1/X) = (2+√3 +2-√3)

=(2+2)

= 4
