Scientific notation Video transcript It always helps me to see a lot of examples of something so I figured it wouldn't hurt to do more scientific notation examples. So I'm just going to write a bunch of numbers and then write them in scientific notation. And hopefully this'll cover almost every case you'll ever see and then at the end of this video, we'll actually do some computation with them to just make sure that we can do computation with scientific notation.
Let me just write down a bunch of numbers. That's my first number. My second number is I'm just arbitrarily stopping the zeroes.
The next number is 0. If I keep saying 0, you might find that annoying. The next number I'm going to do is the number The next number I'll do -- I'm having a lot of 7's here. And then let's just do one more just for, just to make sure we've covered all of our bases.
Let's say we do and then let's throw some -- an arbitrary number of 0's there. So this first one, right here, what we do if we want to write in scientific notation, we want to figure out the largest exponent of 10 that fits into it.
So we go to its first non-zero term, which is that right there. We count how many positions to the right of the decimal point we have including that term. So we have one, two, three. So it's going to be equal to this.
So it's going to be equal to 8 -- that's that guy right there -- 0. So everything after that first term is going to be behind the decimal.
Another way to think of it: Each of these is thousands. Let's do this one. Let's see how many 0's we have. We have 3, 6, 9, So we want to do -- again, we start with our largest term that we have. Our largest non-zero term. In this case, it's going to be the term all the way to the left.
So it's going to be 7. It's going to be equal to 7. Well it's going to be times 10 to the 1 with this many 0's. So how many things?
We had a 1 here. Then we had 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 0's. I want to be very clear. You're not just counting the 0's. You're counting everything after this first term right there. So it would be equivalent to a 1 followed by 12 0's. So it's times 10 to the twelfth.
Let's do this one right here. So we go behind our decimal point.It is important to cite sources in the introduction section of your paper as evidence of the claims you are making. There are ways of citing sources in the text so that the reader can find the full reference in the literature cited section at the end of the paper, yet the flow of the reading is not badly interrupted.
