-5 to a set number is -5
the only real number equal to 75 is 75.3×5×5=75
Real numbers are all numbers. So the answer would be -4 and every number after that in the negative direction. So any number that is less than -4. So, -5, -6, and so on.
5 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
All real numbers.
A real number is a rational number that is not imaginary. 5, 3/4, and 8.6 are all real numbers. 3i is not a real number.

Some examples of sets of real numbers include: The set of positive integers: {1, 2, 3, 4, ...} The set of rational numbers: {1/2, -3/4, 5/6, ...} The set of whole numbers: {..., -2, -1, 0, 1, 2, ...} The set of natural numbers: {0, 1, 2, 3, 4, ...} The set of irrational numbers: {√2, π, e, ...}
Here are some: 5, -2, 1/3, square root of 27, pi.The set of real numbers is a subset of the set of complex numbers. Any complex number can be represented in the form (a + bi), where a & b can be any real number, and i is the imaginary unit equal to sqrt(-1). So if b = 0, then we have just a, which is a real number.
on the real number line there are 2 values with |5|, ie +5 and -5. on the complex plane there are an infinite set of values with an absolute value of 5, ie all the points of distance 5 from the origin.
Prime and odd numbers
The integers. Also: the rational numbers, the real numbers and (depending on your definition) the complex numbers.
