00:00:00.240 --> 00:00:02.899 A:middle L:90%
So for the next problem will be calculating the number
2
00:00:02.899 --> 00:00:06.820 A:middle L:90%
of sick picks for this number. Eso whatever.
3
00:00:06.820 --> 00:00:09.900 A:middle L:90%
You're giving something in scientific notation and you want to
4
00:00:09.900 --> 00:00:13.279 A:middle L:90%
calculate the number of sick pigs. Um, it
5
00:00:13.279 --> 00:00:17.570 A:middle L:90%
is best to write out the scientific notation impossible.
6
00:00:18.239 --> 00:00:22.690 A:middle L:90%
Eso Here we have 5.2100 times 10 something in the
7
00:00:22.699 --> 00:00:30.899 A:middle L:90%
fourth eso if we write it out here because this
8
00:00:30.899 --> 00:00:33.179 A:middle L:90%
is being multiplied by 10 to the negative fourth.
9
00:00:33.189 --> 00:00:37.310 A:middle L:90%
That means our decimal place is moving toward the left
10
00:00:37.320 --> 00:00:39.780 A:middle L:90%
. Because if it were positive, uh, eventually
11
00:00:39.789 --> 00:00:45.219 A:middle L:90%
right, um and so we can write zeros here
12
00:00:45.229 --> 00:00:47.229 A:middle L:90%
and the decimal place. We moved to a lot
13
00:00:47.229 --> 00:00:52.950 A:middle L:90%
four times. So 1234 So then our new number
14
00:00:53.229 --> 00:01:03.149 A:middle L:90%
of U 0.0 five to 2100 eso again for sig
15
00:01:03.149 --> 00:01:06.430 A:middle L:90%
figs. These heroes, you don't count because there
16
00:01:06.430 --> 00:01:08.730 A:middle L:90%
are place holders and so we'll be counting all of
17
00:01:08.730 --> 00:01:11.829 A:middle L:90%
the significant figures after the zeros. So that means
18
00:01:11.829 --> 00:01:21.370 A:middle L:90%
we have one thio three 456 So we have six
19
00:01:21.370 --> 00:01:27.069 A:middle L:90%
numbers se fakes. And this is because anything that
20
00:01:27.069 --> 00:01:33.060 A:middle L:90%
is non zero will contribute one significant figure zeros that
21
00:01:33.060 --> 00:01:37.159 A:middle L:90%
are sandwiched between two non zero numbers also contribute,
22
00:01:37.640 --> 00:01:42.359 A:middle L:90%
um, to the significant number account and trailing zeroes
23
00:01:42.340 --> 00:01:48.129 A:middle L:90%
, Um that are after a decimal place also contribute
24
00:01:48.140 --> 00:01:51.849 A:middle L:90%
to significant figures, and so we have six in
25
00:01:51.849 --> 00:01:53.359 A:middle L:90%
total for this number.
