Any real number - positive or negative - has exactly one real cube root. Any real number (except zero) has three cubic roots in the complex numbers; but only one of them is real.

What are all the real cube roots of 0.125?
They are 0.5 : it is a triple root.
What is the nonnegative square root?
Every positive real number has two square roots: one negative and one positive. As a result, the square root mapping is one-to-many and so is not a mathematical function. One way to make it a function is to restrict the range to non-negative real numbers. These are the non-negative square roots.
Are real numbers closed under the square root operation?
No. Negative numbers are real but their square roots are not.
What is the real number root of sqrt -144?
Negative numbers have no real square roots.-144 has two square roots: 12i and -12i.
Do every polynomial function has at least one complex zero?
No. Complex zeros always come in conjugate pairs. So if a+bi is one zero, then a-bi is also a zero.The fundamental theorem of algebra says"Every polynomial equation of degree n with complex coefficients has n roots in the complex numbers."If you want to know how many complex root a given polynomial has, you might consider finding out how many real roots it has. This can be done with Descartes Rules of signsThe maximum number of positive real roots can be found by counting the number of sign changes in f(x). The actual number of positive real roots may be the maximum, or the maximum decreased by a multiple of two.The maximum number of negative real roots can be found by counting the number of sign changes in f(-x). The actual number of negative real roots may be the maximum, or the maximum decreased by a multiple of two.Complex roots always come in pairs. That's why the number of positive or number of negative roots must decrease by two. Using the two rules for positive and negative signs along with the fact that complex roots come in pairs, you can determine the number of complex roots.
How many real cube roots does any positive number have?
there is no cube roots in negative
Is negative 6 and 6 the real cube roots of 216?
no, -6 is the cube root of -216.
Can you cube root negative two?
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.
What is the cube root of 2?
There are 3 cube roots and these are:the real root -1.2599and the complex roots 0.6300 - 1.0911i and its conjugate, 0.6300 + 1.0911i.
How Many real cube roots dose 1 have?
1
What can be determined from roots of real numbers?
The short answer is "Nothing". In the complex domain, the number of nth roots of any real number is n. Every non-negative real number has 2 square roots. Every real number has 3 cube roots. Every non-negative real number has 2 real square roots and 2 imaginary ones. and so on. So what?
Are there any real roots in negative sixty?
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.
What is the real cube roots of 0.064?
The cube root of 0.064 is 0.4
What is the Real cube roots of 0.000343?
0.07
What is the Real cube roots of 0.125?
3√0.125 = 0.5 (there is only 1 real cube root of 0.125).
Why are there two integer answers for square roots but only one integer answer for cubed roots?
When (if) you learn more advanced mathematics you will find that there are, in fact 3 cube roots for any non-zero number (in the complex field). In general, there are n nth roots (de Moivre's theorem). However, only one of the cube roots can be a real number, the other two are complex numbers. The reason is that the product of a pair of negative numbers is positive. As a result both x and -x are square roots of x^2. But the product of three negative numbers is itself negative, so for cube roots the signs match up.
How many cubed roots are there in number 27?
There are 3 cube roots of 27. There are 2 square roots of 27 ( or any real number ). There are 4 fourth roots of 27 and so on:)
