Exercise
$\lim_{x\to-4}\left(\frac{x+4}{x^2-16}\right)$
Step-by-step Solution
Learn how to solve limits by factoring problems step by step online. Find the limit of (x+4)/(x^2-16) as x approaches -4. Simplify \sqrt{x^2} using the power of a power property: \left(a^m\right)^n=a^{m\cdot n}. In the expression, m equals 2 and n equals \frac{1}{2}. Calculate the power \sqrt{16}.
