In the context of algebra, the term real root refers to the solution to an equation which consists of a real number rather than an imaginary or complex number (a complex number being a combination of real and imaginary numbers). You may recall that any given equation will have the same number of roots (or solutions) as the highest exponent in the equation, so that if you are dealing with x squared, you have two roots. Often there would be one real root and one imaginary root. In general, the real roots are more useful, although there are some circumstances in which imaginary or complex roots are also relevant to what you are doingl.
The square root of seven is a real number, but it is not a whole number.
-0.8 and +0.8
Yes. It's 9. The square root of every positive real number is a real number.
yes, you can find a real root to the cube root of any negative real number. There will also be two complex roots which satisfy it, as well.
the square root of 25 is 5
There is no real number [square] root of a negative number. There is a real cube root and a real fiftth root etc, but root, by itself, implies square root.
The root word in "really" is "real."
The real fourth root of 0.0001 are -0.1 and +0.1
Any odd root, for example the cube root, of -3.24 is a real number.
What does this question mean? -60 has a real cube root, a real fifth root. In fact a real nth root for all odd n.
1+x2 is a polynomial and doesn't have a real root.
Yes. The square root of 25 is 5, which is a real number.
The square root of 0 is 0, which is a real number.
The square root of any positive real number (as in this case) is a real number. (Such square roots are usually irrational.)The square root of a negative real number, such as the square root of -15, is an imaginary, and therefore also a complex, number.
The square root of seven is a real number, but it is not a whole number.
the root word is real. Cuz realistic means 'condition of being real'.
-0.8 and +0.8
