The cube root of 54 isn't an integer. 2 x 2 = 4, the cube root of 64.

It is: -2

54 = 2 x 27 = 2 x 33

-54 is not a perfect cube; thus, the answer contains cube roots. Because this site doesn't allow us to insert images in answers, we'll let C(x) represent "the cube root of X" such that C(8) = 2, etc. The answer, then, is 3 * C(-2).

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">

minus the cube root of 2, or about -1.26

It's the same as the negative of the cube root of 2.

It is -1.2599, approx.

2 cube root 6

They are not, other that the fact that any perfect square is a non-negative and so is also a cube root of some non-negative integer (usually much larger). But -2 is a cube root (of -8), while -8 is not a perfect square.

2 cube root 24 plus 3 cube root 81 is 18.7492444

The cube root of 2 is 1.2599210498948732 (rounded).The cube root of 3 is 1.4422495703074083 (rounded).

To cube a number, you would multiply the number three times. The cube root is the root of the number before it is multiplied. For example, 2 times 2 times 2 is 8, so the cube root is 2.

The cube root of 8 is 2.

the cube root of 25

The cube root of 2/9 is 0.606 approx.

8 = 2 x 2 x 2 and hence cube root of 8 is 2

the inverse of the cube root of x is 2

the cube root of 125 is 5, the cube root of 64 is 4, the cube root of 27 is 3, the cube root of 8 is 2, and the cube root of 1 is 1.

27 = the cube of 3 = 54/2

it is the number which when multiplied by itself three times give you the original number. For example, the cube root of 8 is 2 (2x2x2 = 8) This works for negative numbers as well Forexample, the cube root of -27 is -3 [(-3)x(-3)x(-3) = -27]

When two negative or two positive numbers are multiplied together, they always result in a positive number; and when a positive and a negative number are multiplied together, they will always result in a negative number. Thus, you cannot square root a negative number because there are no real numbers that, when squared, would result in a negative number. For example: (-2)(-2) = 4 (2)(2) = 4 √4 = +/- 2 √(-4) = ? No real number, when squared, is a negative! Does not exist! The cube of a number is different, because you are multiplying three numbers together instead of just two. As a result, you can get a negative or a positive number. For example: (-2)(-2)(-2) = -8r (2)(2)(2) = 8 3√8 = 2 3√(-8) = -2

Cube root is represented as to the power of 1/3.Squared is represented as to the power of 2.A cube root squared is therefore equal to the power of 2 x 1/3 = 2/3.
