00:00:00.540 --> 00:00:04.860 A:middle L:90%
Okay. So for this problem we start off with
2
00:00:04.860 --> 00:00:07.500 A:middle L:90%
the function that were given, but we can rewrite
3
00:00:07.500 --> 00:00:10.109 A:middle L:90%
it. We can turn this into the natural log
4
00:00:10.109 --> 00:00:20.210 A:middle L:90%
of Y equals the limit um of the natural log
5
00:00:20.219 --> 00:00:22.350 A:middle L:90%
. We can move the natural log on the outside
6
00:00:22.350 --> 00:00:25.500 A:middle L:90%
. So we have the natural log of the limit
7
00:00:25.510 --> 00:00:31.250 A:middle L:90%
of our function that will allow us to rewrite things
8
00:00:31.260 --> 00:00:34.409 A:middle L:90%
. So once we rewrite it we can get that
9
00:00:34.409 --> 00:00:38.259 A:middle L:90%
. The natural log of why equals the limit of
10
00:00:38.259 --> 00:00:43.759 A:middle L:90%
-2 times the natural log I have one over the
11
00:00:43.759 --> 00:00:48.820 A:middle L:90%
square root of X Divided by one over the square
12
00:00:48.820 --> 00:00:50.750 A:middle L:90%
root of X. The reason why we want to
13
00:00:50.759 --> 00:00:52.200 A:middle L:90%
do this is so we can make this A.
14
00:00:52.200 --> 00:00:56.070 A:middle L:90%
T. And now as X approaches zero from the
15
00:00:56.070 --> 00:01:00.630 A:middle L:90%
right, he is approaching infinity. Then we'll use
16
00:01:00.630 --> 00:01:03.369 A:middle L:90%
local tells role in order to take the derivative of
17
00:01:03.369 --> 00:01:06.099 A:middle L:90%
the top and bottom. This will end up giving
18
00:01:06.099 --> 00:01:07.629 A:middle L:90%
us zero. But keep in mind that we made
19
00:01:07.629 --> 00:01:10.870 A:middle L:90%
this, the natural log of Y equals zero.
20
00:01:10.879 --> 00:01:12.560 A:middle L:90%
So based on that we'll see that why has to
21
00:01:12.560 --> 00:01:15.049 A:middle L:90%
equal one for the final answer.
