What is Cube Root?
The cube root is a mathematical operation that calculates the value which, when multiplied by itself three times (raised to the power of 3), gives a specific number. In other words, it is the reverse operation of cubing a number. The cube root is denoted by the symbol ∛ and is used to find the principal cube root of a number.
For example, the cube root of 8 is represented as ∛8, and it is equal to 2 because 2 × 2 × 2 = 8. Similarly, the cube root of -27 is represented as ∛(-27), and it is equal to -3 because -3 × -3 × -3 = -27.
All Formulae Related to Cube Root
The cube root is a mathematical operation used to find the number that, when raised to the power of 3, equals a given value. Here are the primary formulas related to the cube root:
- Cube Root Formula:
- The cube root (∛a) of a number “a” is represented by:
- ∛a = b, where “b” is the cube root of “a.”
- Cube Root Calculation:
- To calculate the cube root of a number “a,” you can use the following formula:
- ∛a = a^(1/3)
- Cubing Formula:
- The process of cubing a number “b” means raising it to the power of 3:
- b^3 = b × b × b
- Cube Root as an Inverse Operation of Cubing:
- The cube root and cubing operations are inverse of each other:
- If ∛a = b, then b^3 = a, and vice versa.
- Cube Root of a Negative Number:
- The cube root of a negative number “a” is the negative of the cube root of its absolute value:
- ∛(-a) = -∛|a|
- Cube Root of a Fraction:
- To calculate the cube root of a fraction, you can take the cube root of both the numerator and the denominator separately.
- Cube Root of a Complex Number:
- In advanced mathematics, you can calculate the cube root of complex numbers using techniques like De Moivre’s theorem and polar form.
- Cube Root Identities:
- There are various cube root identities and properties that can be used in algebraic manipulations and simplifications.
