$\lim_{x\to1}\left(\frac{x^2-1}{1-x}\right)$
Soluzione passo-passo
Impara online a risolvere i problemi di passo dopo passo. (x)->(1)lim((x^2-1)/(1-x)). 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=1, b=\frac{1}{2} e a^b=\sqrt{1}.
