Lots of numbers do.
To begin, all real numbers do.
Multiples of sqrt(-1), aka. imaginary numbers, do.
The Complex Numbers are all numbers which are the sum of a real number and an imaginary number.

Which set of numbers does 9 belong to?
9 belongs in the sets: -Natural number set, positive whole numbers -Integer number set, whole numbers -Rational number set, numbers that are not never ending -Real number set, basic numbers without i and that can be expressed in say amounts of apples -Complex number set, the set that contains both real and unreal numbers
To which set of numbers does the number -12 belong?
It belongs to any set that contains it: for example, {4.75, -12, pi, sqrt(5), 29}. It belongs to the set of integers which is a proper subset of rational numbers which is a proper subset of real numbers which is a proper subset of complex numbers. So -12 belongs to all the above sets.
What is a complex set?
The set of complex numbers is the set of numbers which can be described by a + bi, where a and b are real numbers, and i is the imaginary unit sqrt(-1). Since a and b can be any real number (including zero), the set of real numbers is a subset of the set of complex numbers. Also the set of pure imaginary numbers is a subset of complex number set.
Is an imaginary number always sometimes or never a complex number?
Always. The set of imaginary numbers is a subset of complex numbers. Think of complex numbers as a plane (2 dimensional). The real numbers exist on the horizontal axis. The pure imaginary are the vertical axis. All other points on the plane are combinations of real and imaginary. All points on the plane (including imaginary axis and real axis) are complex numbers.
What number set contains the number -5?
To any set that contains it! It belongs to {-5}, or {-5, sqrt(2), pi, -3/7}, or all whole numbers between -43 and 53, or multiples of 5, or negative integers, or rational numbers, or real numbers, or complex numbers, etc.
The number -4 is what set of numbers?
The number -4 belongs to the set of all integers. It also belongs to the rationals, reals, complex numbers.
Which set of numbers does -17 belong to?
It belongs to any set that has -17 amongst its members.Given that this is schoolwork, the answer teacher probably wants is: the set of integers.It also belongs to the set of rational numbers, the set of negative integers, the set of real numbers, the set of complex numbers, the set {43.2, 98, -17, pi} and an infinite number of others.It belongs to the set of complex numbers in spite of having no 'imaginary' part. Real numbers are just special cases of complex number in which the imaginary part happens to be zero. Rational numbers are special cases of real numbers. Integers are special cases of rational numbers.
What number categories does -3.75?
Negative rational numbers; Negative real numbers; Rational numbers; Real numbers. The number also belongs to the set of complex numbers, quaternions and supersets.
What set of numbers does -2 belong to?
-2 belongs in the sets: -Integer number set, whole numbers -Rational number set, numbers that are not never ending -Real number set, basic numbers without i and that can be expressed in say amounts of apples -Complex number set, the set that contains both real and unreal numbers
Which set of numbers does 9 belong to?
9 belongs in the sets: -Natural number set, positive whole numbers -Integer number set, whole numbers -Rational number set, numbers that are not never ending -Real number set, basic numbers without i and that can be expressed in say amounts of apples -Complex number set, the set that contains both real and unreal numbers
What Name the set (s) of numbers that 1.18 belongs?
It belongs to the set ofrational numbers,decimal fractions,improper fractions (in decimal form),real numbers,complex numbers,quaternions.
Name the sets of numbers to which negative 10 belongs?
Of the "standard sets" -10 belongs to: ℤ⁻ (the negative integers) ℤ (the integers) ℚ⁻ (the negative rational numbers) ℚ (the rational numbers) ℝ⁻ (the negative real numbers) ℝ (the real numbers) ℂ (the complex numbers) (as ℤ ⊂ ℚ ⊂ ℝ ⊂ ℂ). Other sets are possible, eg the even numbers.
To which set of numbers does the number -12 belong?
It belongs to any set that contains it: for example, {4.75, -12, pi, sqrt(5), 29}. It belongs to the set of integers which is a proper subset of rational numbers which is a proper subset of real numbers which is a proper subset of complex numbers. So -12 belongs to all the above sets.
What subsets of the real numbers does the number 25.6 belong?
It belongs to the interval (25, 27.3), or [-20.9, 10*pi], and infinitely more such intervals.It also belongs to the set of rational numbers, real numbers, complex numbers and quaternions.
What is the difference between a set of real numbers and a set of complex numbers?
The set of real numbers is a subset of the set of complex numbers. For the set of complex numbers, given in the form (a + bi), where a and b can be any real number, the number is only a real number, if b = 0.
What set of numbers does -14 belong to?
There are many sets of numbers -14 belongs to:set of negative integersset of rational numbersset of real numbersset of complex numbers, which is the biggest known number set
What set of numbers does the number -6 belong to?
It belongs to infinitely many sets. Some notable sets to which it belongs include:* Integers * Negative integers * Rational numbers * Real numbers * Complex numbers
