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:)
How many fourth roots do numbers have?
Usually four. As a simple example, the fourth roots of 1 are: 1, -1, i, -i.
If a is a positive real number and n is even how many roots are there?
Assuming that you mean the nth. root: two - a negative and a positive root.
How many square roots can a positive number have?
Every positive number has two square roots, though the roots are not always whole numbers (or even rational numbers). The more obvious of each numbers roots is the positive one.The positive square root of 4 is 2, because 2*2=4.The positive square root of 5 is roughly 2.236068.The other square root of a number is the negative inverse of their positive root. This is because when two negative numbers are multiplied together the negative signs "cancel out", leaving a positive number.The negative square root of 4 is -2, because -2*-2=4.The negative square root of 5 is roughly -2.236068.Zero has only one square root, itself, and no negative number has any (real number) square roots, since no number multiplied by itself will result in a negative.
How many square roots does a postitive number have?
2, a positive and a negative eg 9 = 3 x 3 and -3 x -3
How many real cube roots does any positive number have?
there is no cube roots in negative

How many square roots does 7 have?
Every number has two square roots. They're the same size, but one is positive and the other is negative.
How many square roots does the number 13 have?
Every positive number has TWO square roots. The principal square root is the positive number which, when multiplied by itself, gives the number in question. But its negative equivalent will also be a square root. For example, the number 4 has 2 as the principal sqrt but -2 is also a sqrt of 4

How many square roots does every number have?
All positive numbers have two. 0 has only one. Negative numbers have two imaginary roots but no real ones.
How many square roots dose a positive number have?
The square root of positive number can be ether a matched set of positive or negative numbers. As an example the square root of 4 can be either (-2 x -2) or (+2 x +2)
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 square roots dose a negative number have?
no,a negative number cannot have a square root .it is made only for positive numbers .but,yes,negative numbers can be squared.
