There is no such number. All of these sets go on forever.
All non prime numbers have factors that are primes.
Real numbers are all numbers which do not contain "i", when "i" represents the square root of -1. All numbers which do contain "i" are "imaginary numbers" and are not real numbers. This means that all numbers you'd ordinarily use are real numbers - all the counting numbers (integers) and all decimals are real numbers. So in answer to your question, all the real numbers that are not whole numbers are all the decimal numbers - including irrational decimals such as pi.
Each integer is a whole number and each whole number is an integer. So the set of all integers is the same as the set of all whole numbers. By the equivalence of sets, integers and whole numbers are the same.
501
No, because there are an infiite number of sets that contain -5. For example {-5, 8}, which does not even have a name.
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.
The number 15 belongs to an infinite amount of sets.
The union is all the numbers in all the sets.
There is no such number. All of these sets go on forever.
With math for most people, the set of complex numbers can be considered to enclose all other sets of numbers.There are, however, sets of numbers that have been created which are outside the scope of 'complex numbers'.
You can make lots of sets that contain the number 74, for example:{74} {73, 74, 75} {0, 74, 8, 99} The set of integers The set of real numbers The set of complex numbers
To any set that contains it! It belongs to {-8}, or {45, sqrt(2), -8, pi, -3/7}, or all whole numbers between -43 and 53, or multiples of 2, or composite numbers, or negative counting numbers, or integers, or rational numbers, or real numbers, or complex numbers, or cubes of integers, etc.
A number set is simply a collection of numbers. The numbers in a set need not share any property whatsoever - the only requirement is that they are all numbers.
All of them.
they are almost all equivalent - whole numbers also have the number 0, which natural numbers (counting numbers) do not.
0.1296714785 is a real number. All numbers that do not contain the square root of a negative number (represented by i) are real numbers.
