$\frac{\sqrt{b^2-a}-\sqrt{b^2-a}}{a-a}$
Learn how to solve problems step by step online. Find the limit (x)->(a)lim(((b^2-x)^1/2-(b^2-a)^1/2)/(x-a)). Evaluate the limit \lim_{x\to a}\left(\frac{\sqrt{b^2-x}-\sqrt{b^2-a}}{x-a}\right) by replacing all occurrences of x by a. Cancel like terms \sqrt{b^2-a} and -\sqrt{b^2-a}. Cancel like terms a and -a. \frac{0}{0} represents an indeterminate form.
