In the complex field, the number of roots is the same as the index. Complex (non-real) roots come in pairs (complex conjugates) so the number of real roots will also be odd.

What does radical mean in mathematics?
A radical is the sign √ which is used to indicate that a root must be calculated. The full format is n√ which indicates that it is the nth root that is required. For square roots the prefix is usually excluded. [As a result many people wrongly assume that the radical sign refers only to square roots.]
How many solutions will a problem have if the discriminant is positive?
Two real roots.
How many solutions will a problem have if the discriminant is zero?
Two equal roots
What are radical and index?
The radical is the diving board that looks like a dividing symbol but has a check mark at the beginning. Inside the check mark is the index. If there is not one then it is understood to be a 2 for square root. If a 3 is in the check mark it is cube root. The root is how many times you use a factor to get a number. The cube root of 27 is 3 because 3x3x3 =27.
What is the index of a square root?
The index is 2. If we have the nth root of a number, the index is n. The index means how many times do we multiply the number by itself. So for square roots, we do it twice. For example, square root of 9 is 3 because 3x3 is 9 and index is 2. Cube root of 8 is 2 since 2x2x2=8 so the index is 3 since we multiplied 2 by itself 3 times

What is a radical in social studies?
Following is a knowledge on radicals which will help you to get solution to algebra problems. A radical is a root sign. Radicals require an index to define what root it is. With square roots, the two is generally left off. With cube roots (index of three) a 3 is written on top of the left side of the radical. The index tells how many times the root needs to be multiplied by itself to equal the radicand.We can even generalize and find the nth root which would be a number multiplied by itself n times to equal the radicand.Ex.Square root of 9.2 is the index and 9 is the radicand. The square root of 9 is 3. This means that 3 x 3 = 9Cube root of 64.3 is the index and 64 is the radicand. The cube root of 64 is 4. This means that 4 x 4 x 4 = 64One last thing to think about, we can also write the index, for exampe 2 in the square root of 9, as a fractional exponent. So 9(1/2) is another way of writting the square root of 9 and 64(1/3) is another way of saying the cube root of 64.Now the law of exponents say (am)n= amn so, if we have the square root of 9 raised to the power 2 we have(91/2)2 = 9(2/2) =91 =9 which helps us to see how we relate square root and square of a number.The concept of radical is very, very important in algebra. Among other reasons, it was proven by Ruffini, and more later more rigorously by Abel, in 1824, that quintic (and higher) equations cannot be solved in radicals. There are solutions to these higher equations, but these solutions require methods from numerical analysis or from the theory of elliptic functions, rather than algebraic factorization into radicals.For solving radical equations get help from math all time. This will help you to learn about radicals in algebra.

Is range is not considered to be an index of despersion?
The sample range could be used as an index of dispersion. However, there are objections. One is that this statistic is obviously sensitive to outliers. Another is that for many population distributions there are measures with much better characteristics, even ignoring the problem of outliers.
