it's 4 man have a nice day

Answer 2

Answer:The correct answer is 4.

Explanation:

Put the values of a in the given question.

2-root 3 +1/2-root 3

=Then as result Lcm would be 2-root 3

So, [(2-root3)^2+1]/2-root3

=(4+3-4root 3+1)/2-root3

=(8-4root3)2-root3

=Now, take 4 as common from the numerator,

4(2-root3)/2-root3

=2-root 3 gets cancelled from both and 4 left as our answer.
