I just tried to simplify (4+sqrt(3))/(5-sqrt(3)); but there is a radical in the denominator in the answer.

Tried
load("sqdnst")$
sqrtdenest((4+sqrt(3))/(5-sqrt(3)));
but it does not help.

"No square root in the bottom" should be considered as the canonical form of simplified expression.

    Use ratsimp(...), algebraic:

    (%i1)   ratsimp((4+sqrt(3))/(5-sqrt(3))),algebraic;
    (%o1)   (3^(5/2)+23)/22
