Aug 17, 2023 · Use this calculator to find the cube root of positive or negative numbers. Given a number x, the cube root of x is a number a such that a3 = x. If x is positive a will be positive. If x is negative a will be negative. The Cube Root Calculator is a specialized form of our common Radicals Calculator.
In mathematics, a cube root of a number x is a number y such that y 3 = x. All nonzero real numbers have exactly one real cube root and a pair of complex conjugate cube roots, and all nonzero complex numbers have three distinct complex cube roots.
Cube root of number is a value which when multiplied by itself thrice or three times produces the original value. For example, the cube root of 27, denoted as 3 √27, is 3, because when we multiply 3 by itself three times we get 3 x 3 x 3 = 27 = 3 3.
Cube root of a number can be found by a very simple method which is the prime factorization method. Cube root is denoted by ‘∛ ‘ symbol. Example: ∛8 = ∛ (2 × 2 × 2) = 2. Since, 8 is a perfect cube number, it is easy to find the cube root of a number.
It is easy to work out the cube root of a perfect cube, but it is really hard to work out other cube roots. Example: what is the cube root of 30? Well, 3 × 3 × 3 = 27 and 4 × 4 × 4 = 64, so we can guess the answer is between 3 and 4.
The cube root of a number is the value being multiplied by itself three times. Cube rooting a number is the inverse operation of cubing a number. The cube root function looks like this \sqrt [3] {\quad} 3 where 3 3 is the index of the root. The cube root sign can also be called a radical sign.
If you have a much larger number here, yes, there's no very simple way to compute what a cube root or a fourth root or a fifth root might be and even square root can get quite difficult. There's no very simple way to just calculate it the way that you might multiply things or divide it.
