2/(1+sqrt(3))
Multiply and divide by (1-sqrt(3))
= 2*(1-sqrt(3)) / [(1+sqrt(3))*(1-sqrt(3))]
= 2*(1-sqrt(3)) / [1 -3]
= -1 * (1 - sqrt(3))
= sqrt(3) -1

If you want to in decimal, then
= 1.732 - 1
= 0.732

Multiply and divide by (1-sqrt(3))
= 2x(1-root(3)) / [(1+root(3))x(1-root(3))]
= 2x(1-root(3)) / [1 -3]
= -1 x(1 - root(3))
= 0.732 (3 decimal places)
