Use the root test to determine if the series from 1 to infinity of $\frac{1}{4^n}$ will converge or diverge.

Use the root test to determine if the series $\left(\frac{3+5n}{2+3n}\right)^n$ converges, diverges, or is inconclusive.

Apply the root test to the series $\left(\frac{1}{n^2 + \frac{1}{n}}\right)^n$.

Use the root test on the series $\left(\frac{n^n}{2^{1+4n}}\right)$ to determine its convergence or divergence.

Look at the Taylor polynomial for $\cos(x)$ and we're cutting it off at degree 4, $T_4(x)$. We want to figure out what values of $x$ you can plug in there for it to be accurate to two decimal places.
