$\lim_{x\to\infty }\left(\left(\sqrt{x+8}-\sqrt{x+7}\right)\frac{\sqrt{x+8}+\sqrt{x+7}}{\sqrt{x+8}+\sqrt{x+7}}\right)$
Learn how to solve limits by rationalizing problems step by step online. Find the limit of (x+8)^(1/2)-(x+7)^(1/2) as x approaches infinity. Applying rationalisation. Multiply and simplify the expression within the limit. Cancel like terms x and -x. Evaluate the limit \lim_{x\to\infty }\left(\frac{1}{\sqrt{x+8}+\sqrt{x+7}}\right) by replacing all occurrences of x by \infty .
