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