How to find cube root easily?​

Answer 1

Step-by-step explanation:

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.

Finding the cubic root of non-perfect cube number is a little complex process but can be mastered easily. To find the cube root of any number, we need to find a number which when multiplied three times by itself gives the original number.

Let us learn here finding cube root using prime factorisation method and solved examples. Also, find the cubes and cube roots of 1 to 15 numbers here in the table given.

The cube root of any number say ‘a’, is the number ‘b’, which satisfies the equation given below:

b3 = a

This can be represented as:

a = ∛b

Answer 2

Answer:

In math, the cube root formula is used to represent any number in the form of its cube root, such as for any number x, its cube root will be 3√x = x1/3. For example, the cube root of 125 is 5 because 5 × 5 × 5 = 125.
