They are called conjugates.

They Are Both Real Numbers.
All factors are whole numbers and all whole numbers are rational numbers (a rational number is one which can be expressed as one integer over another integer, and whole numbers can be expressed as themselves over 1), thus all factors are rational numbers and so all greatest common factors are rational numbers. The set of whole numbers is a [proper] subset of the set of rational numbers: ℤ ⊂ ℚ
Real numbers are composed of rational and irrational numbers. Integers are part of the group (set) of rational numbers. And the integers are composed of the counting numbers (1, 2, 3, ...) and their negative counterparts (-1, -2, -3, ...). Oh, almost forgot. There is one more integer that is neither positive or negative. It's the number zero. Zero is an integer (neither positive or negative). The smallest real number ever is zero.
Square numbers have an odd number of factors.
real numbers, irrational numbers, ...
Neither, it is an imaginary number and imaginary numbers are neither rational nor irrational.
Imaginary numbers are not a subset of the real numbers; imaginary means not real.
real and imaginary rational and irrational
Imaginary numbers are not intrinsically rational or irrational.Of course, all real numbers are either rational or irrational numbers.Imaginary numbers are not real numbers.Imaginary numbers have a real part and an imaginary part, sometimes written like z=x+i y.The two parts, i.e. the x and the y, are real numbers. As real numbers, they are either rational or irrational. Its just that the two parts of a complex number may both be either rational or irrational or one may be rational and the other irrational. One could always make up a new name for these cases, but right now there is no such classification.
Numbers are split into real and imaginary. Rational numbers are under the category: Real. Therefore all rational numbers are real. An irrational number is also real, but can not be expressed as a fraction.
yes * * * * * No. Rational and irrational numbers are two DISJOINT subsets of the real numbers. That is, no rational number is irrational and no irrational is rational.
No, but it is irrational, because there is no rational number whose square is two. Imaginary numbers are the square roots of negative numbers.
No. None are because the opposite of a real number is an imaginary number. In real numbers there are rational, irrational, counting, whole numbers, and integers.
No. Irrational numbers are real numbers, therefore it is not imaginary.
real number, imaginary, irrational rational integers, positive and negative
All irrational numbers are not rational.
All integers are rational numbers. There are integers with an i behind them that are imaginary numbers. They are not real numbers but they are rational. The square root of 2 is irrational. It is real but irrational.
