Intro

Hi, welcome to discussion right here. So we're trying to calculate a square root of 16. Now, with your calculator in your hand, of course if you just punch it in your calculator, you gonna get yourself something, okay. And this thing gives us, a 4, okay. What I did on my calculator, I don't know why; you should know that numbers make a perfect square numbers really well like the 16... Square root of 16 is a 4, square root of 25 is a 5, stuff like that. But let's say you forgot how to do it, okay. So, you have to use something that's called the prime factorization, I'll do that very quickly; so 16 right here if you divide it by 2, you get yourself 8, and if you divide it by 2 again you get yourself a 4, and if you divided it by 2 again of course you get... At the very end it's just a 2 left. So, what you have is a square root of 2 x 2 x 2 x 2, okay. This is equivalent to the 
? 16, so far. Now when you do this, remember, if you're doing the square root, I can group these guys into a pair and I can group these guys into a pair. And the reason I'm doing that is to show you the steps. So what happens if you're doing the square root, right? There's a 2 here, it means that for every number that you have inside here underneath a radical, if you have two of them together. So, anything with the squares, you can just take that number and bring it out of the radical. So you can just solve a 2 right now on the outside, just one, not both of them. Just take one of them to come out. Now there's another one right here with 2 squared, okay. It's 2 squared, there's a, there's a pair of them. So we can also take this one out of the radical as well, so if you do that you'll get yourself another 2 on the outside, okay. Now there's nothing else left over in the radical so technically it's a 1. So square root of 1 is just 1, so it disappeared, okay. So what's 2 x 2 at the end? Well you get yourself a 4 as your final answer which is the same as... If you use a calculator, is exactly the same answer, okay. Thanks for watching.

This lesson focuses on finding the square of a whole number and the square root of a perfect square. In order to do this, we will first learn how to do prime factorization, a method to find the prime factors of a number.
