00:00:00.540 --> 00:00:03.930 A:middle L:90%
All right. Hi everyone. So today we're gonna
2
00:00:03.930 --> 00:00:08.240 A:middle L:90%
be working on scientific notation. Under the rules of
3
00:00:08.240 --> 00:00:12.949 A:middle L:90%
exponents. in our example, we have the length
4
00:00:12.960 --> 00:00:17.850 A:middle L:90%
of a hydrogen oxygen burn inside of a water molecule
5
00:00:18.440 --> 00:00:21.030 A:middle L:90%
. And the problem, it says that this is
6
00:00:21.039 --> 00:00:31.649 A:middle L:90%
0.000000001 millimeters. We're going to be writing this into
7
00:00:31.649 --> 00:00:36.810 A:middle L:90%
scientific notation. What I like to do is first
8
00:00:36.820 --> 00:00:41.320 A:middle L:90%
circle boxing or underlying all of my numbers that are
9
00:00:41.320 --> 00:00:45.850 A:middle L:90%
not zero. In this case we have 1.
10
00:00:46.640 --> 00:00:50.149 A:middle L:90%
So what I'm going to do is write 1.0,
11
00:00:50.740 --> 00:00:56.539 A:middle L:90%
Which is the equivalent to 1 times 10 To a
12
00:00:56.539 --> 00:00:59.770 A:middle L:90%
certain degree. However, we don't know what this
13
00:00:59.780 --> 00:01:03.120 A:middle L:90%
degree is. So we're going to count, how
14
00:01:03.120 --> 00:01:07.049 A:middle L:90%
many times will we have to move this to get
15
00:01:07.049 --> 00:01:11.650 A:middle L:90%
to 1.0. But before we start we can simply
16
00:01:11.650 --> 00:01:14.590 A:middle L:90%
just look at the number and already see that this
17
00:01:14.599 --> 00:01:19.510 A:middle L:90%
is less than one. Which means our exponent will
18
00:01:19.510 --> 00:01:25.200 A:middle L:90%
be negative. Yeah. Oh, So now to
19
00:01:25.200 --> 00:01:26.769 A:middle L:90%
get this to 1.0, we're going to be moving
20
00:01:26.769 --> 00:01:30.180 A:middle L:90%
this to the right. This move will be going
21
00:01:30.180 --> 00:01:33.930 A:middle L:90%
to the right And we're going to count how many
22
00:01:33.930 --> 00:01:36.790 A:middle L:90%
times we move this decimal to the right to get
23
00:01:36.790 --> 00:01:48.790 A:middle L:90%
our desire number. So let's count 123456789. To
24
00:01:48.790 --> 00:01:51.909 A:middle L:90%
get 1.0 will be moving this nine times to the
25
00:01:51.909 --> 00:01:53.939 A:middle L:90%
right. Would you give us to the negative night
26
00:01:53.939 --> 00:02:01.629 A:middle L:90%
power? Which means our answer will be 1.0 Times
27
00:02:01.640 --> 00:02:08.009 A:middle L:90%
10 to the-9 mm. Do not forget the
28
00:02:08.009 --> 00:02:12.759 A:middle L:90%
units. Thank you guys for watching.
