So we have to use the limit comparison test to determine if this function is convert the series converges or not.
00:13
In order to do that, we have to determine which one is going to be the series that we are going to use to compare with.
00:21
For that, let's check at the top.
00:24
We are going to choose a series that has the same sort of degree.
00:33
On top and on the bottom.
00:35
So for example, that be 2 to the end, in this case over 5 to the end.
00:42
The concept of degree is not exactly what we are doing.
00:47
We are taking the element that has the biggest magnitude here.
00:52
And we know that this series converges because it's a geometric series with r equals to 2 over 5.
01:01
Now let's calculate the limit when n goes to infinity of the general term of our series and the series that we want to compare with.
01:13
Let's rearrange the terms.
01:21
Okay...
