Cube Roots
A cube root is a number that, when multiplied by itself three times, produces the original number. For example, the cube root of 8 is 2, because 2 multiplied by itself three times equals 8. The cube root of 125 is 5, because 5 multiplied by itself three times equals 125.
What is Cube Root?
Cube Root is a mathematical operation which is used to extract the cube root of a number. The cube root of a number is the number which when multiplied by itself three times gives the original number. For example, the cube root of 27 is 3 because 3 multiplied by itself three times gives 27.
Calculation of Cube Root of 216
The cube root of 216 is 6.
Prime Factorisation Method
The prime factorisation method is a way of finding the prime factors of a number.
The prime factors of a number are the prime numbers that are factors of the number.
To find the prime factors of a number, divide the number by the prime numbers that are factors of the number.
The prime factorisation of a number is the list of the prime numbers that are factors of the number, in order from smallest to largest.
Simplify Algebraic Cube Root
The cube root of a number is the number that results when you take the cube root of each number in the number and add them all together. To simplify the cube root of a number, you can factor out the common cube root.
Use of Cube and Cube Roots
A cube is a three-dimensional figure that is formed by six identical squares that are connected together. The cube has 12 identical square faces, 8 vertices, and 24 edges.
The cube root of a number is the number that is multiplied by itself three times to get the original number. For example, the cube root of 64 is 4 because 4 multiplied by itself three times is 64.
Cube Root of a Negative Number
There is no real root to a negative number. However, there are imaginary roots to a negative number.
