there are 5 diffeerent sets Natural Numbers whole numbers integers rational numbers irrational numbers.
from the numbers 4567 we can have 24 numbers
The sets of numbers that are the Square root of 5 are: 25 125
They are all sets that contain it. It belongs to {-400}, or {-400, sqrt(2), pi, -3/7}, or {-400, bananas, France, cold} or all whole numbers between -500 and -300, or multiples of 5, or negative composite numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.

15504 different sets of 5 numbers in each. This is a combination of 5 from 20: 20C5 = 20!/(20-5)!5! = 20x19x18x17x16/5x4x3x2x1 = 15504.

i dont undstand exactly what your asking but the name for it is a phythangorean triple like 3,4, & 5
5 is a member of the sets of counting numbers (positive integer), integers, rationals, reals. It is also a member of the set of irrational numbers, complex numbers and numbers in higher dimensions where the "other" parts are zero.

The (operation) union in mathematics usually refers to sets of numbers and means the combination of those sets. The best way to describe it is to use an example: Take some set A with the numbers 1, 2, 3, 4, 5 in it and some set B with the numbers 1, 3, 5, 7, 9 in it. The union of these two sets would be the list of all things (list of elements) that is in EITHER set. As long as something is in one of the sets, it's in the union of the sets. Going with the example, the union of these two sets would be 1, 2, 3, 4, 5, 7, 9. Note though that you do NOT count something twice if it's in both sets, it's only counted once.
