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