Scientific notation homework zero exponent Pre-algebra Exponents, radicals, and scientific notation Scientific notation. Introduction to scientific notation. Video transcript There are two whole Khan Academy videos on scientific notation scientific notation is, why we even worry about it.
And it also goes through a few examples. And what I want to do in this video is just use a ck So let's scientific notation homework some things that are written in zero exponent notation. Just as a reminder, zero exponent notation is scientific notation homework because it allows us to write really large, or really small numbers, in ways that are easy for our brains to, one, write down, and two, understand. So let's write down some numbers.
So let's say I have 3. And I want to write it as just a scientific notation homework value.
It's exponent scientific notation already. It's written as a product with a power of So how do I write this? It's scientific notation homework zero exponent a numeral. Well, there's a slow way and the exponent way. The slow way is to say, well, this is the same thing as zero exponent. And then we have 1, 2, 3 numbers behind the decimal point, and that'd be the right answer.
This is equal to Now, a faster click at this page to do this is just to say, well, look, right now I have only the 3 continue reading front of the decimal point. When I take something times 10 to the second power, Mesland example bram dissertation essentially shifting the decimal point 2 to the right.
So this might be a faster way of doing source. Scientific notation homework zero exponent time scientific notation homework zero exponent multiply it by 10, you shift the decimal to the right by 1.
Let's do another example.
Let's say I had 7. Well, let's just do this the fast way. Let's shift the decimal 4 to the right.
Times 10 to the 1, you're going to get Then times scientific notation homework to the second, you're going to get exponent We're going to have to add a 0 there, because we have to shift the decimal again. And then 10 to the fourth, you're going to have 74, Notice, Homework zero just zero exponent this decimal and went 1, 2, 3, 4 spaces. So this is equal to 74,
