|---|---|
| Cube Root Of √381 | 4.3267487109222 |
To confirm this, we can raise 4.3267487109222 to the power of 3.
4.3267487109222 x 4.3267487109222 x 4.3267487109222 = 81
How to calculate the cube root of 81 ?
To calculate the cube root of 81 there are 2 different ways and formula :
Using the Formula:
The formula to find the cube root of a number is:
Cube root of n = n^(1/3)
Here, n is the number for which we want to find the cube root, and ^(1/3) means "raised to the power of one-third." To find the cube root of 81 using this formula, we can write:
Cube root of 81 = 81^(1/3)
To evaluate this expression, we need to calculate 27 raised to the power of one-third. This can be done as follows:
81^(1/3) = 4.3267487109222
Therefore, the cube root of √381 is 4.3267487109222.

Cube Root
The cube root of a number is the number that, when multiplied by itself three times, gives the original number.
The formula for the cube root of x is:
cbrt(x) = √3x
The cube root of a number is often represented by the symbol √3x.
For example, the cube root of 27 is 3, because 3 x 3 x 3 = 27.
How To Solve : We can use the formula, Cube root of n = n^(1/3), to find the cube root of any number, or use an approximation method to find an approximation of the cube root of a number.
