# How to write an exponential notation with positive exponents video

And then I multiplied the exponents. It's equal to 1. We'll worry about that at the end. So this I can write as-- I take the leading digit-- 1. The slow way is to say, well, this is the same thing as 3. And this is a valid answer.

So it's going to be 7. We're going to have to add a 0 there, because we have to shift the decimal again.

You're not just counting the 0's. One, two, three. I don't know when I'm going to stop.

### Exponential notation of 512

And then you're going to have your decimal. Let's do 0. It's that one right there, so it's going to be 6 times and then how many terms do we have to the right of the decimal? In this lesson, we will learn an introduction to exponents and rules of exponents multiplication and division properties of exponents zero and negative exponents scientific notation simplifying expressions with exponents The following figure gives the Rules of Exponents. So this is equal to 74, So I don't want to change the number. Let's shift the decimal 4 to the right. Let's divide this guy by that guy. Multiply the decimal number by 10 raised to a power of n. Let me divide this by And how did I know 4 0's? So if we have 3. One, it'll be easier to represent these numbers and then hopefully you'll see that the multiplication actually gets simplified as well. Let me just write down a bunch of numbers. Let's start with something that's written as a numeral and then write it in scientific notation.

And you have 1, 2, 3, 4, 5, 6 digits. Just to mix things up.
