Step by step simplification process to get cube roots radical form and derivative: First we will find all factors under the cube root: 1331 has the cube factor of 121. Required fields are marked *. The cube root of 729, denoted as 3 √729, is a value which after getting multiplied by itself thrice gives the original value. 1. (iii) Combine the like square root terms using mathematical operations. Step II : Resolve it into prime factors. Step 1: Make group of 3 digit, starting from right Step 2: The unit digit of cube root will be Unit digit of cube root of 4913 = Unit digit of cube root of 913 Since 503 ends in 3, it’s cube root will end in 7. Therefore, 11 is the cube root of a given number 1331. Recently I have created a YouTube Channel called Murali Maths Class, check for the latest Maths Videos on All the topics. Here, we will use the prime factorisation method to find the prime factors of 2197. This is the usual definition of the cube root of a number. Your email address will not be published. Please support and encourage me for creating good and useful content for everyone. The fastest method to find the value of the cube root of a four-digit number, 2197, is the estimation method. The result is 27. ∴ Cube root of 1331 = 11 Find cube root of 4913. A number m is the cube root of a number n if n = m 3. 1728 as a product of prime numbers. Now let us proceed to calculate the value of 3√2197 following these steps: Take the digit present at the unit’s place of 2197. E-learning is the future today. After that, we will pair the factors in a group of three to represent them as cubes. That means the cubic root of 2197 will have 3 at the unit place.
