In solutions to quadratic equations, and higher order equations, it is usual, in most cases, to have more than one solution. A solution such as the square root of minus one is said to be imaginary as there are no real numbers that can be squared that give you the result of minus one. There is a branch of mathematics called complex numbers that you would need to study to understand in depth but it is a useful tool for representing and performing calculations in heavy electrics (amongst other things) where equipment may be powered by three phase currents.
Nearly any number you can think of is a Real Number. So 8 is a real number.
no, every number is a real number --- There are numbers that are not real numbers. They are called imaginary numbers, and have the property that when they are squared, the result is negative. The square root of -1 is called i, and the square root of any other negative number is i times the square root of the absolute value of the number. So the square root of -4 is 2i.
A real number is any number so yes it is always a real number * * * * * Except if the second number is 0, in which case the quotient is not defined.
Yes. The set of whole numbers (more usually called Integers) is a strict subset of the set of Real Numbers.
What is her number so I could call memphitz and toya
3233196060 it so real i called it try it
Yes. A real number is any number that could be plotted on a number line. For example, 3/4 could be plotted on a number line, and so it is real. Only square roots of negative numbers are not real: they are called imaginary.
Yes! Every complex number z is a number, z = x + iy with x and y belonging to the field of real numbers. The real number x is called the real part and the real number y that accompanies i and called the imaginary part. The set of real numbers is formed by the meeting of the sets of rational numbers with all the irrational, thus taking only the complex numbers with zero imaginary part we have the set of real numbers, so then we have that for any irrational r is r real and complex number z = r + i0 = r and we r so complex number. So every irrational number is complex.
Yes a real number is a natural since real is natural so anything real is natural and so a real number is natural.
The point on a number line that corresponds to a number is called an "ordered pair" of a real number.
Yes. That is his real numebr.. i called him
It is a real number.
The other real number is 3/pi. I will bet that was not the real number you had in mind and so is an "other" real number.
Nearly any number you can think of is a Real Number. So 8 is a real number.
A whole number IS a real number so you do not have to do anything.
yes that is a real number because i called it and they answered the phone
