Cube Root of 125/216

Professor Greenline Explaining Math Concepts

A number we multiply by itself three times to get the original number is its cube root. It has various uses in real life, such as finding the volume of cube-shaped objects and designing structures. We will now find the cube root of 125/216 and explain the methods used.

What is the Cube Root of 125/216?

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, ∛(125/216) is written as (125/216)(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 125/216, then y3 can be 125/216. Since 125 and 216 are both perfect cubes, we can express the cube root of 125/216 as (∛125)/(∛216), which simplifies to 5/6.

Finding the Cube Root of 125/216

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 125/216. The common methods we follow to find the cube root are given below:

 

  • Prime factorization method
  • Simplification method

 

Since 125/216 is a fraction made of perfect cubes, we can use the simplification method to find its cube root.

Cube Root of 125/216 by Simplification Method

Let's find the cube root of 125/216 using the simplification method.

The formula is ∛(a/b) = (∛a)/(∛b) where: a = the numerator b = the denominator

Substituting, a = 125; b = 216 ∛(125/216)

= (∛125)/(∛216)

Since 125 = 53 and 216 = 63, we find:

∛125 = 5 and ∛216 = 6

Thus, ∛(125/216) = 5/6

The cube root of 125/216 is 5/6.
