Does Limit[] not know about L'Hospital?
In[1]= (2 Mi OmegaSyn Rr-3 sk^2 Us^2+
Sqrt[-4 Mi^2 OmegaSyn^2 Rr^2 sk^2+9 sk^4 Us^4])/(2 Mi Rr)
Out[1]=
2 2
(2 Mi OmegaSyn Rr - 3 sk Us +
2 2 2 2 4 4
Sqrt[-4 Mi OmegaSyn Rr sk + 9 sk Us ]) / (2 Mi Rr)
In[2]= Limit[%, Mi->0]
Out[2]=
2 2 4 4
Infinity (-3 sk Us + 3 Sqrt[sk Us ])

Rr
In[3]= Limit[ D[Numerator[%%], Mi]/ D[Denominator[%%], Mi]
,Mi->0 ] (* Is L'Hospital possible? *)
Out[3]= OmegaSyn
