one of the measurements to the third power
x cube = x*x*x for any number x.
V= x^3
For variable m and n, the word "square" means m2 and "cube" means m3. The equation becomes m2 - n3 = 16.
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.
radical equations have sq roots, cube roots etc. Quadratic equations have x2.
V=lbh (length x breadth x height)
height by width Ex H5 by W5 = Area 25
There is no volume of a square, but a cube has volume and its equation is V=lenght*width*height or because all of the sides are equal for a cube side*side*side
A cube has equal sides. If one side is equal to 3 feet.... The equation: V = X*X*X (or Xcubed)
The equation of the volume of a cube is s^3, where 's' is the length of one edge. So the edge would be the cubed root of the volume. In your case, the cube root of 200. Which is 5.848 (approx).
y = c*x3 where c is the constant of proportionality.
First, this is an expression, not an equation. As far as simplifying it, it's pretty much simplified as much it can be.
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">
