a root number is a number in which satifies the unknown value of an equation.
For example:
x² - 1 = 0
the root of this equation would be 1 or -1 since when multiplied by itself, they both equal 1. Therefore, 1 - 1 = 0
The root of any equation is a number which ... when substituted for the variable ...makes the equation a true statement.
I assume you mean, in an equation. Such a number is called a "solution" or a "root" of the equation.
A solution or root makes a true statement when substituted in an equation.
Such a value is said to be a solution, or a root, of the equation.
If the negative number is "-a", then you can say the cube root is "-(cube root of a)" Because if you cube a negative number, you get a negative number. So if you cube root a negative number, you get a negative number. Ex) cube root of -8 = -2 Because (-2)^3 = -8 But if you want to find the complex cube roots, you can make an equation: "x^3=-a" or "x^3+a=0" We know one of the roots is "-(cube root of a)" so you can factor the equation by (x+(cube root of a)) And then you use the quadratic formula for the quadratic equation you're left with. Ex) x^3=-8 or x^3+8=0 Since -2 is a root, factor it by (x+2) x^3+8=(x+2)(x^2-2x+4) Using the quadratic formula, you get "1+i√3" and "1-i√3" Therefore the three cube roots of -8 is <"-2", "1+i√3", "1-i√3">
The root of any equation is a number which ... when substituted for the variable ...makes the equation a true statement.
In mathematics, the term "root" refers to the solution(s) of an equation. Specifically, the roots of an equation are the values that make the equation true when substituted for the variable. The number of roots depends on the degree of the equation.

An algebraic number is a complex number which is the root of a polynomial equation with rational coefficients.
A solution or root makes a true statement when substituted in an equation.
The square root of 41 is an irrational , algebraic, real number. It is real, is the root of an polynomial equation with integer coefficients, but can not be expressed as a ratio of integers.
The solution of the equation.
To get rid of a cubed number in an equation, you need to take its cube root. For example, if you have x raised to the third power is equal to 2 raised to the third power, then one takes the cube root of both sides of the equation to find that x is equal to 2.
A positive number has two square roots, that is, there are two solutions to an equation like x2 = 100. The "principal square root" refers to the positive solution.
Root means solution in this context.
if you have a TI-84 you can hit math, then go down to the x before the square root sign
roots of equation are x values when y = 0
