Q. Which statement best describes the limit shown below?x→∞limx88+exlnx+10x20The limit equals zeroThe limit does not existThe limit exists and does not equal zero
Analyze Behavior: We need to analyze the behavior of the numerator and the denominator as x approaches ∞ to determine the limit.
Numerator Growth: The numerator lnx+10x20 grows without bound as x approaches infinity, but at a much slower rate than x20 because the logarithmic function grows slower than any polynomial.
Denominator Growth: The denominator x88+ex also grows without bound as x approaches infinity. However, ex grows much faster than any polynomial, including x88.
Comparison of Growth Rates: Since ex in the denominator grows faster than any term in the numerator, the fraction as a whole approaches zero as x approaches infinity.
Limit Conclusion: Therefore, the limit of x88+exlnx+10x20 as x approaches infinity is 0.
