How do you find the cube root of a negative number?
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">

What is the square root of 192?
5.76899828 orFactor the 192:=8x24=8 x 8 x 3remember that cube root of 8 is 2, so you have:2 x 2 (cube root of 3) = 4 cube root of 3for the x^9, cube root is x^(9/3) = x^3final answer:4x^3(cube root 3)that's' it! ;)
What is the difference between a cube and a cube root?
The cube of a number is the value of the number multiplied by itself two times (or 1 multiplied by the number three times). A cube root is the inverse function so that if y is the cube of x the x is the cube root of y.
