## How to Calculate the Value of the Cube Root of 54?

### Cube Root of 54 by Halley"s Method

Its formula is ∛a ≈ x ((x3 + 2a)/(2x3 + a)) where, a = number whose cube root is being calculated x = integer guess of its cube root.

Here a = 54 Let us assume x as 3 <∵ 33 = 27 and 27 is the nearest perfect cube that is less than 54> ⇒ x = 3 Therefore, ∛54 = 3 (33 + 2 × 54)/(2 × 33 + 54)) = 3.75 ⇒ ∛54 ≈ 3.75 Therefore, the cube root of 54 is 3.75 approximately.

## Is the Cube Root of 54 Irrational?

Yes, because ∛54 = ∛(2 × 3 × 3 × 3) = 3 ∛2 and it cannot be expressed in the form of p/q where q ≠ 0. Therefore, the value of the cube root of 54 is an irrational number.

## FAQs on Cube Root of 54

### What is the Value of the Cube Root of 54?

We can express 54 as 2 × 3 × 3 × 3 i.e. ∛54 = ∛(2 × 3 × 3 × 3) = 3.77976. Therefore, the value of the cube root of 54 is 3.77976.

### What is the Cube of the Cube Root of 54?

The cube of the cube root of 54 is the number 54 itself i.e. (∛54)3 = (541/3)3 = 54.

### Why is the Value of the Cube Root of 54 Irrational?

The value of the cube root of 54 cannot be expressed in the form of p/q where q ≠ 0. Therefore, the number ∛54 is irrational.

### What is the Value of 5 Plus 4 Cube Root 54?

The value of ∛54 is 3.78. So, 5 + 4 × ∛54 = 5 + 4 × 3.78 = 20.119999999999997. Hence, the value of 5 plus 4 cube root 54 is 20.119999999999997.

### Is 54 a Perfect Cube?

The number 54 on prime factorization gives 2 × 3 × 3 × 3. Here, the prime factor 2 is not in the power of 3. Therefore the cube root of 54 is irrational, hence 54 is not a perfect cube.
