Nov 27, 2006  Best Answer: The square root of 1 cannot be a real number, because there's no number which, when multiplied by itself, gives 1. So the square root of any negative number cannot be a real number, because for any number n, it is equal to 1 x n. You can take the square root ofAny point on the line is a Real Number: The numbers could be whole (like 7) or rational (like 209) or irrational (like ) But we won't find Infinity, or an Imaginary Number. Why are they called Real Numbers? Because they are not Imaginary Numbers. The Real Numbers had no name before Imaginary Numbers were thought of. not a real number example

This number is not 1, not 1, not 0, not any other number between infinity and infinity. This number is the imaginary (opposite of real) unit, often represented with the number i. If you multiply i by any nonzero real number and add it by any real number, youll get a nonreal number. (i itself is not real). The simplest and most wellknown example is this: find a subset [mathV[math of the interval [math[0, 1[math with the property that every real number is a rational distance away from exactly one point in [mathV[math.not a real number example In mathematics, real is used as an adjective, meaning that the underlying field is the field of the real numbers (or the real field). For example, real matrix, real polynomial and real Lie algebra. The word is also used as a noun, meaning a real number (as in the set of all reals ). Generalizations and extensions

A square root of a number is a number that when multiplied by itself yields the original number. For example, 4 is a square root of 16, because 4 162. Since 4 16 2, we can say that 4 is a square root of 16 as well. Every positive real number has two square roots, one positive and one negative. not a real number example Irrational Numbers. An Irrational Number is a real number that cannot be written as a simple fraction. . Irrational means not Rational. Let's look at what makes a number rational or irrational Rational Numbers A Rational Number can be written as a Ratio of two integers (ie a simple fraction). A nonreal, or imaginary, number is any number that, when multiplied by itself, produces a negative number. Mathematicians use the letter i to symbolize the square root of 1. An imaginary number is any real number multiplied by i. For example, 5i is imaginary; the square of 5i is 25. Aug 27, 2008 A complex number has a real portion and an imaginary portion. For example, three plus the square root of negative seven. That's not real and it's not imaginary. It's complex. If the link works, check my answer to the other question. This just means that even if a number looks odd, or has a strange symbol or Greek letter associated with it, it's still a real number. Let's look at a couple of examples: 14 0. 25
