What is the limit as x approaches 3 of (sqrt(x+1)2)/(x3). I'm having a lot of difficulty figuring this one out algebraically as you don't have to ratonalize the denominator. Please help.Thank you very much. 

Hi Abraham, I would rrationalize the numerator by multiplying both the numerator and denominator by sqrt(x+1)2. This gives a numerator of
and a denominator of
Since x is not 3 you can cancel the (x3)Factors and get
