For the Limit Comparison Test, identify the dominant terms in the numerator and denominator to find a simpler comparison series. The denominator suggests comparing to `\frac{1}{n^3}` for the first case or `\frac{1}{n^4}` for the second case. Calculate `\lim_{n o \infty} \frac{a_n}{b_n}` where `b_n` is your comparison series.
