$\frac{\sqrt{x}-7}{\left(\sqrt{x}+7\right)\left(\sqrt{x}-7\right)}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit (x)->(49)lim((x^1/2-7)/(x-49)). Factor the difference of squares x-49 as the product of two conjugated binomials. Simplify the fraction . Evaluate the limit \lim_{x\to49}\left(\frac{1}{\sqrt{x}+7}\right) by replacing all occurrences of x by 49. Calculate the power \sqrt{49}.
