please answer both questions from your own work on a paper providing all steps for good feedback.

9. A series is absolutely convergent if the series of its absolute values is convergent Every absolutely convergent series is convergent If a series is convergent but not absolutely convergent, it is called conditionally convergent. a] Use the alternating series test to show that this series converges. \"Elem\": b] Demonstrate whether the series above is absolutely convergent or conditionally convergent. 10. The ratio and root test can be used to show absolute convergence. a] Use the ratio test to determine the convergence or divergence of the series. Z\"\"\"() b] Explain why the root test is the best choice for the series below. Then use it to determine the convergence or divergence of the series. Elf\"+10%\" fun2 n=1
