Calculus 2: Ratio and root tests

Utilize the root test for series with terms that include powers like (something)n(\text{something})^n.

Apply the ratio test to series involving factorial terms and powers, such as those with n!n! or similar structures.

Use the ratio test to determine the convergence of the series nnn!\frac{n^n}{n!}.

Use the root test to determine if the series (3+5n2+3n)n\left(\frac{3+5n}{2+3n}\right)^n converges, diverges, or is inconclusive.

Apply the root test to the series (1n2+1n)n\left(\frac{1}{n^2 + \frac{1}{n}}\right)^n.

Use the root test on the series (nn21+4n)\left(\frac{n^n}{2^{1+4n}}\right) to determine its convergence or divergence.

Determine if the series (n2n)\displaystyle \left(\frac{n}{2^n}\right) converges or diverges using the root test.

Apply the root test to the series (1)n3n+2(n1)n(-1)^n \cdot \frac{3^{n+2}}{(n-1)^n} to determine if it converges or diverges.

Using the Ratio Test or the Root Test, determine if the infinite series an\sum a_n converges or diverges.

Apply the root test to check if a series converges absolutely or diverges.

Using the ratio or root test, determine if the series [{ "type" : "katexPlugin", "text": "\sum a_n", "inline": true }]', is absolutely convergent.
