Q. Which statement best describes the limit shown below?\newlinelimxlnxx46+10x91 \lim _{x \rightarrow \infty} \frac{\ln x}{x^{46}+10 x^{91}} \newlineThe limit equals zero\newlineThe limit does not exist\newlineThe limit exists and does not equal zero
  1. Given Limit Expression: We are given the limit expression limxlnxx46+10x91\lim_{x \to \infty}\frac{\ln x}{x^{46}+10x^{91}}. To determine the behavior of this limit, we need to analyze the growth rates of the numerator and the denominator as xx approaches infinity.
  2. Analysis of Growth Rates: The numerator lnx\ln x grows logarithmically, which is much slower than any positive power of xx. The denominator has two terms: x46x^{46} and 10x9110x^{91}. As xx approaches infinity, the term with the highest power of xx will dominate the growth of the denominator. In this case, it's the 10x9110x^{91} term.
  3. Comparison of Numerator and Denominator: Since the denominator grows much faster than the numerator, the fraction as a whole will approach 00 as xx approaches infinity. This is because the denominator's growth will make the fraction's value smaller and smaller.
  4. Conclusion: Therefore, the correct statement that describes the limit is: "The limit equals 00."
