So now that we know the major parts of scientific notation, let's put it to practice with this example question. Here it says which of the following scientific notation values is written correctly. So if we take a look at A here, we have 1.25×10-14. Well, if we look the coefficient, this part here is fine. It's a number between 1:00 and 10:00. Here our base is 10, but our error is that the exponent is not a whole number integer, it's -14. This is not written correctly.
Next, if we take a look at the very beginning, we see that our coefficient here is a number that is not between 1:00 and 10:00. This is not allowed for scientific notation. The base is correct and the exponent is a whole number. But again, the coefficient is not a number between 1:00 and 10:00, so this will not work.
First C we have our coefficient Wiz which is a number between 1:00 and 10:00, so this is allowed. Our base is 10 and our exponent is a whole number integer 3. So this is a correct way of writing something within scientific notation values. So this is our answer.
If we look at D though, for D our coefficient again is a number between 1:00 and 10:00. But our base here, our base is not ten, it's two. Remember, if you're writing something in scientific notation, the base is always 10. The exponent is correct, but it's the base that's making it incorrect overall.
So again, remember the three components of scientific notation and the limits that they each have. Following that ensures that your right scientific notation correctly every time.
