You need to remove the radical from denominator, hence, you should multiply by `(root(3)(16) + 2root(3)(4) + 4)` such that:

`(root(3)(16) + 2root(3)(4) + 4)/((root(3)(4) - 2)(root(3)(16) + 2root(3)(4) + 4)) = (root(3)(16) + 2root(3)(4) + 4)/(4 - 8)`

`1/(root(3)(4) - 2) = (root(3)(16) + 2root(3)(4) + 4)/(-4)`

**Hence, rationalizing the fraction yields `1/(root(3)(4) - 2) = (root(3)(16) + 2root(3)(4) + 4)/(-4).` **
