$\frac{\sqrt{x}-2}{\left(\sqrt{x}+2\right)\left(\sqrt{x}-2\right)}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit of (x^1/2-2)/(x-4) as x approaches 4. Factor the difference of squares x-4 as the product of two conjugated binomials. Simplify the fraction . Evaluate the limit \lim_{x\to4}\left(\frac{1}{\sqrt{x}+2}\right) by replacing all occurrences of x by 4. Calculate the power \sqrt{4}.
