$\lim_{x\to2}\left(\frac{x^2-4}{-x+2}\right)$
Soluzione passo-passo
Impara online a risolvere i problemi di passo dopo passo. (x)->(2)lim((x^2-4)/(-x+2)). 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}. Applicare la formula: a^b=a^b, dove a=4, b=\frac{1}{2} e a^b=\sqrt{4}.
