Exercise

$\lim_{x\to\infty}\left(\left(\frac{-x^2-1}{-x^2+2}\right)^{-3x-1}\right)$

Step-by-step Solution

1

Rewrite the limit using the identity: $a^x=e^{x\ln\left(a\right)}$

$\lim_{x\to\infty }\left(e^{\left(-3x-1\right)\ln\left(\frac{-x^2-1}{-x^2+2}\right)}\right)$
2

Multiplying polynomials $\ln\left(\frac{-x^2-1}{-x^2+2}\right)$ and $-3x-1$

$\lim_{x\to\infty }\left(e^{\left(-3x\ln\left(\frac{-x^2-1}{-x^2+2}\right)-\ln\left(\frac{-x^2-1}{-x^2+2}\right)\right)}\right)$
3

Simplify $e^{\left(-3x\ln\left(\frac{-x^2-1}{-x^2+2}\right)-\ln\left(\frac{-x^2-1}{-x^2+2}\right)\right)}$ by applying the properties of exponents and logarithms

$\lim_{x\to\infty }\left(\left(\frac{-x^2-1}{-x^2+2}\right)^{-3x}e^{-\ln\left(\frac{-x^2-1}{-x^2+2}\right)}\right)$
4

Evaluate the limit $\lim_{x\to\infty }\left(\left(\frac{-x^2-1}{-x^2+2}\right)^{-3x}e^{-\ln\left(\frac{-x^2-1}{-x^2+2}\right)}\right)$ by replacing all occurrences of $x$ by $\infty $
