Hi, my name is Marija, I'm a mathematician. And today, I'm going to show you how to simplify a number to the third power. So, if I have a number like two to the third power. What this means, is that I'm going to multiply this number, which is called the base by itself, three times. That's what that three indicates, it tells me to multiply this base by itself three times. So, I'm writing two times two, times two and now, I'm just going to simplify this. So, two times two, is four. I'm going to bring down my other two that I haven't used, and four times two, is eight. So, two to the third power is equal to eight. We'll do another example, if I have five to the third power. Again, that three tells me to multiply five by itself three times. So, I'm doing five times five, times five. Five times five is 25, bring down that other five. Now, I'm doing 25 times five, think of five quarters, I'm going to go down to 25, right, so that becomes 125. So, five to the third power is 125. So, whenever you raise a number to the third power, all you're doing is, taking that number and multiplying it by itself three times. My name is Marija, and I just showed you how to simplify a number raised to the third power.
