So 10 times 10 times 10 times 10 times 10. We're going to take five 10s and multiply them together. Up to you on the street and say what is 10 to the fifth power? What is that? What number that you're probably familiar with would this be? Well this would mean that Well as you might have imagined, we were taking 10 10s and Write it using exponents? Pause the video and figure that out. Number here, 10 billion? What's a way that we could You can show that you moved it 6 places to the right by noting that the number should be multiplied by 10-6. If you ever saw 10 to the third power, that means hey, let me We would read this asġ0 to the third power. Might have imagined, we're taking a certain number of 10s and we see we're taking three 10s and we're multiplying them together. Times 10 times 10 or 1000? How would you write that using exponents? Pause this video and see So 10 to the second power is 10 times 10 is equal to 100. Some of the parts of this, the two would be called the exponent and the 10 would be the base. That looks fancy, but all that means is let's take two 10s and multiply them together and we're going to get 100. Multiplying them together, I could write this as 10 to the second power. And so 10 times 10, we can rewrite as being equal to, if I have two 10s and I'm So the way they do this is through something known as exponents. To write things like this a little bit more elegantly. So mathematicians haveĬome up with a notation and some ideas to be able Kinda hard to write, and imagine if we have 30 10s that we were multiplying together. This right over here is 10 billion, and it's already getting We put the commas there so it's just a little bit easier to read. One, two, three, four, five, six, seven, eight, nine, 10. It's going to be oneįollowed by 10 zeroes. This is going to be equal to, even the number that it's equal to is going to be quite hard to write. Let's see, one, two, three, four, five, six, seven, eight, nine, 10. That's four, that's five, that's six, that's seven, that's eight, that's nine, that is 10 10s. So if I were to go 10 times 10 times 10 times 10,
POWER OF TEN SHOW HOW TO
The following diagram shows how to multiply and divide. But at some point, if I'mĭoing this with enough 10s, it gets pretty hard to write. When dividing by powers of 10, move the decimal point one place to the left for each power of ten. Multiply them together, so 10 times 10, which Powers of ten are written like 10x, where x is whatever power Im talking about and. In this video, I'm going to introduce you to a new type of mathematical notation that will seem fancy at first, but hopefully you'llĪppreciate is pretty useful and also pretty straightforward. These are simple examples to show you that you already know how this works.
