1. The problem statement, all variables and given/known data lim as x approached 2 from above of: (x1/2 - 21/2 + (x - 2)1/2)/(x2 - 4)1/2 2. Relevant equations L'Hopitals rule... 3. The attempt at a solution I tried susbtituting in 2 and found that I got 0/0 thus it was possible to use L'hopitals. I then got inf/inf, so I used it again, but now I keep getting inf/inf. So what do I do? I'm stumped. I tried factorising but the + and - signs prevented me.
