Hello there.
00:03
We are given a set of numbers and we have to determine whether those numbers in our set are a, natural numbers, b, whole numbers, c, integers, d, rational numbers, e, irrational numbers, or f, real numbers and kind of list them in each of those categories.
00:24
All right, really important that in order to be able to list values from a set into these categories, you do have to know the definition.
00:31
So i kind of have some like, brief examples or a quick definition in a sense just to refresh our memories as to what these mean.
00:43
So to get started, a value from our set that is given that falls under a natural numbers is going to be the value of the square root of four.
00:57
Now, the square root of four falls under the natural numbers because if you are to simplify this, this really is the same as two, and two is a natural number.
01:08
All right, four whole numbers, whole numbers encompass natural numbers.
01:12
So the square root of four is a whole number as well as now we can include the number zero from our set...
