Hi. Just to add to the others, if we "Assume" the following
k = (9*Sqrt[3] + 4*Sqrt[23])^ (1 / 3) ;
// Or... k=k//FullSimplify Sqrt[1/2 (13+Sqrt[69])]
Then what you have is:
(k+k) / Sqrt[3.] 3.76887
// Which matches what others have mentioned:
For this to equal 1, then k would have to equal
Sqrt[3] / 2
Perhaps your equation for the k part is off a little. ??
