## How to Calculate the Value of the Cube Root of 625?

### Cube Root of 625 by Halley”s Method

Its formula is ∛a ≈ x ((x3 + 2a)/(2×3 + a)) where, a = number whose cube root is being calculated x = integer guess of its cube root.

Here a = 625 Let us assume x as 8 <∵ 83 = 512 and 512 is the nearest perfect cube that is less than 625> ⇒ x = 8 Therefore, ∛625 = 8 (83 + 2 × 625)/(2 × 83 + 625)) = 8.55 ⇒ ∛625 ≈ 8.55 Therefore, the cube root of 625 is 8.55 approximately.

## Is the Cube Root of 625 Irrational?

Yes, because ∛625 = ∛(5 × 5 × 5 × 5) = 5 ∛5 and it cannot be expressed in the form of p/q where q ≠ 0. Therefore, the value of the cube root of 625 is an irrational number.

## FAQs on Cube Root of 625

### What is the Value of the Cube Root of 625?

We can express 625 as 5 × 5 × 5 × 5 i.e. ∛625 = ∛(5 × 5 × 5 × 5) = 8.54988. Therefore, the value of the cube root of 625 is 8.54988.

### What is the Value of 16 Plus 1 Cube Root 625?

The value of ∛625 is 8.55. So, 16 + 1 × ∛625 = 16 + 1 × 8.55 = 24.55. Hence, the value of 16 plus 1 cube root 625 is 24.55.

### How to Simplify the Cube Root of 625/8?

We know that the cube root of 625 is 8.54988 and the cube root of 8 is 2. Therefore, ∛(625/8) = (∛625)/(∛8) = 8.55/2 = 4.275.

### Is 625 a Perfect Cube?

The number 625 on prime factorization gives 5 × 5 × 5 × 5. Here, the prime factor 5 is not in the power of 3. Therefore the cube root of 625 is irrational, hence 625 is not a perfect cube.
