$\frac{4\cdot 4-1\cdot 4^2}{2-\sqrt{4}}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit (x)->(4)lim((4x-x^2)/(2-x^1/2)). Evaluate the limit \lim_{x\to4}\left(\frac{4x-x^2}{2-\sqrt{x}}\right) by replacing all occurrences of x by 4. Multiply 4 times 4. Calculate the power \sqrt{4}. Multiply -1 times 2.
