It is a bit hard to define them - and the exact definitions are a bit formal. It is best to think of real numbers as the equivalent of all points on a straight line, infinite in both directions.

Define conjugate number?

A conjugate number refers to a complex number having both the imaginary and real parts of opposite signs and equal magnitude.


What are the component of real numbers?

Real Numbers cannot be the square root of a negative number. Real Numbers are not divided by zero. Basically, Real Numbers cannot be anything that is undefined.


Is there a square root of -28?

No, there is no real number that satisfies the equation √(-28). The square root of a negative number is not defined in the real number system. However, if we extend our number system to include complex numbers, we can define a square root of -28 as √(-28) = 2√7i, where i is the imaginary unit.


What best describes an imaginary number?

You can describe it as a number defined such that i squared = -1.You can also define the complex plane first, and then describe an imaginary number as a complex number in which the real part is zero.


Is the zero imaginary number?

An imaginary number is a square root of a negative number. Imaginary numbers have the form bi where b is a non-zero (real number) and i is the imaginary unit, defined as the square root of − 1.if we define 'imaginary numbers' as 'complex numbers having a real part as 'zero' and a non-zero imaginary part'.. 0 doesn't fit in this description. But by, convention and for theoretical symmetry , we'll have to define 'real numbers' in pretty much the same way, and hence 0 would neither be a purely imaginary number or a purely real number.Overall i would say that 0 is a real number. Imaginary numbers only involve square roots of negative numbers.http://wiki.answers.com/Is_the_zero_imaginary_number#ixzz16w9viQWx

Is the square root of seven a real number?

Well, first let's define a "real number." A real number is any number that's not imaginary. It can be rational or irrational. The square root of 7 is 2.64575131... and it goes on forever. This means it cannot be written as a simple fraction. We can give an estimate of the square root of 7 in a fraction form, but this is not the exact result. So, the square root of 7 is a irrational number.Since a real number can be irrational or rational, yes, the square root of 7 is a real number.


How do you define real?
