The cube root of a negative number is negative.

No, the cube root of -9 is an irrational number.

No.

You cannot get real square root of a negative number because two numbers multiplied by themselves are always positive You can always get a real cube root of a negative number because three negative numbers multiplied by themselves give a negative .

yes, you can find a real root to the cube root of any negative real number. There will also be two complex roots which satisfy it, as well.

I am pretty sure that the cube root of negative seven is a surd. I checked on the calculator.......and it showed a negative number.....??I think when it is not a surd...it's supposed to say error, so the number probably means that it is a surd..

Negative 2 (times) cube root of 54 = -7.55953 Negative 2 (plus) cube root of 54 = 1.77976

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">

Yes as for example the cube root of -27 is -3

There is no real number [square] root of a negative number. There is a real cube root and a real fiftth root etc, but root, by itself, implies square root.

minus the cube root of 2, or about -1.26

The cube root of the number 8 is 2(two). Cube Root-a number when multiplied 3 times equals a given number.

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]

A cube root can be any number because any number can be cubed.

To find the cube root of a number, enter the number followed by ^(1/3).To find the cube root of a number, enter the number followed by ^(1/3).To find the cube root of a number, enter the number followed by ^(1/3).To find the cube root of a number, enter the number followed by ^(1/3).

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 number is approximately 199.69 (the cube root of 27^5).

The cube root of -108 is -3*cuberoot(4) The cube root of 3-108 can't be reduced, but it's about 4.7
