How to Calculate the Value of the Cube Root of 500?
Cube Root of 500 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 = 500 Let us assume x as 7 <∵ 73 = 343 and 343 is the nearest perfect cube that is less than 500> ⇒ x = 7 Therefore, ∛500 = 7 (73 + 2 × 500)/(2 × 73 + 500)) = 7.93 ⇒ ∛500 ≈ 7.93 Therefore, the cube root of 500 is 7.93 approximately.

FAQs on Cube Root of 500
What is the Value of the Cube Root of 500?
We can express 500 as 2 × 2 × 5 × 5 × 5 i.e. ∛500 = ∛(2 × 2 × 5 × 5 × 5) = 7.93701. Therefore, the value of the cube root of 500 is 7.93701.
What is the Cube of the Cube Root of 500?
The cube of the cube root of 500 is the number 500 itself i.e. (∛500)3 = (5001/3)3 = 500.
Is 500 a Perfect Cube?
The number 500 on prime factorization gives 2 × 2 × 5 × 5 × 5. Here, the prime factor 2 is not in the power of 3. Therefore the cube root of 500 is irrational, hence 500 is not a perfect cube.
Why is the Value of the Cube Root of 500 Irrational?
The value of the cube root of 500 cannot be expressed in the form of p/q where q ≠ 0. Therefore, the number ∛500 is irrational.
How to Simplify the Cube Root of 500/729?
We know that the cube root of 500 is 7.93701 and the cube root of 729 is 9. Therefore, ∛(500/729) = (∛500)/(∛729) = 7.937/9 = 0.8819.
