Re: L'Hospital's Rule Square Root Problem
Ok sorry, missed that. Anyhow, what about the original problem dealing with L' Hospital's rule. So how did the "x over the square root fraction" come about?

As for the original problem, it does come out to be indeterminate before factoring out. But after factoring, it's not.

Re: L'Hospital's Rule Square Root Problem
Look back to my very first post (post #3). What is the derivative of the expression $\sqrt{x^2 + 3} - 2$? (in terms of x)

Re: L'Hospital's Rule Square Root Problem
1/(b/a) = a/b

would be the reason for the fraction under x.

Yes...and you know how to compute the derivative of the denominator, right?
