In this video we're going to look at simplifying certs but before we start simplifying them let's just remind ourselves what they are thirds are basically nasty square roots if you have the square root of 10 I'll call that a nasty square root because if you do it on a calculator square root of 10 and some calculators you have to press the SD button it's a nasty decimal therefore that is a third whereas if I did the square root of 16 well the square root of 16 is 4 because 4 times 4 is 16 so that's not 1/3 because root of 16 is just 4 and 4 is an integer a whole number so this one is a surd over here this one here is not the basic thing is thirds on nursery square root square roots which come out to be nasty decimals so we're going to look at simplifying some SERDES the first one we're going to look at is simplifying root 40 and you might say well what what we're trying to do in simplifying so it's what you're trying to do is get the smallest number possible inside the square root sign and the other numbers outside the square root sign that's fine and the way to do it is to try and spot what two numbers multiply together to give you 40 okay so one times forty two times 25 times eight four times ten there are various different numbers and multiplied together to give you 40 and you're looking for a pair of numbers where one of them is a square number and if I go for four times by ten four is a square number and that's the one I'm going to use you're always looking for a pair...
