$\frac{2-\sqrt{7-3}}{7^2-49}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit (x)->(7)lim((2-(x-3)^1/2)/(x^2-49)). Evaluate the limit \lim_{x\to7}\left(\frac{2-\sqrt{x-3}}{x^2-49}\right) by replacing all occurrences of x by 7. Subtract the values 7 and -3. Calculate the power 7^2. Subtract the values 49 and -49.
