Cube Root of 34300

We have learned the definition of the cube root. Now, let's learn how it is represented using a symbol and exponent. The symbol we use to express the cube root is the radical sign (∛), and the exponent we use is ⅓.

In exponential form, ∛34300 is written as 34300^(1/3). The cube root is just the opposite operation of finding the cube of a number. For example: Assume ‘y’ as the cube root of 34300, then y³ can be 34300. Since the cube root of 34300 is not an exact value, we can write it as approximately 32.8.

Finding the cube root of a number is to identify the number that must be multiplied three times resulting in the target number. Now, we will go through the different ways to find the cube root of 34300. The common methods we follow to find the cube root are given below:

•  Prime factorization method
•  Approximation method
• Subtraction method
• Halley's method

To find the cube root of a non-perfect number, we often follow Halley's method. Since 34300 is not a perfect cube, we use Halley's method.

Let's find the cube root of 34300 using Halley's method.

The formula is ∛a ≅ x((x³ + 2a) / (2x³ + a))

where: a = the number for which the cube root is being calculated

x = the nearest perfect cube

Substituting, a = 34300;

x = 32 ∛a ≅ 32((32³ + 2 × 34300) / (2 × 32³ + 34300))

∛34300 ≅ 32((32768 + 68600) / (65536 + 34300))

∛34300 ≅ 32.8

The cube root of 34300 is approximately 32.8.

• Cube root: The number that is multiplied three times by itself to get the given number is the cube root of that number.
   
• Perfect cube: A number is a perfect cube when it is the product of multiplying a number three times by itself. A perfect cube always results in a whole number. For example: 2 × 2 × 2 = 8, therefore, 8 is a perfect cube.
   
• Exponent: The exponent form of the number denotes the number of times a number can be multiplied by itself. In a^(1/3), ⅓ is the exponent which denotes the cube root of a.
   
• Radical sign: The symbol that is used to represent a root is expressed as (∛).
   
• Irrational number: Numbers that cannot be put in fractional forms are irrational. For example, the cube root of 34300 is irrational because its decimal form goes on continuously without repeating the numbers.
