We can define a cube root as a number that, when multiplied by itself three times, gives you the original number. The cube of a number is represented as X3 and the cube root of a number is represented as ∛x. Cube roots are used with several applications in our day-to-day lives, such as in the field of Scaling Models and Designs, which helps create miniature models of buildings, aircraft, or cars.
The cube root of 512 is 8. The cube root of 512 is expressed as ∛512 in radical form, where the ∛ sign is called the radical sign. In exponential form, it is written as (512)⅓
We can find the cube root of 512, mainly through two methods:
Finding a cube root of 512 through the Prime Factorization method involves determining the factor of 512.
Step 1 — Find the prime factors of 512.
So the prime factor of 512 is 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2
Step 2 — Group the factors of 512 in a group of 3.
Step 3–We have 9 digits, which makes a set of 3 triplets.
Note: During Prime factorization, a pair of 2 digits is made in square roots, whereas in a cube a triplet is made.
The cube root of 512 can be written as ∛512 = ∛(2 × 2 × 2) × (2 × 2 × 2) × (2 × 2 × 2) = 2 × 2 × 2 = 8. Therefore, the cube root of 512 is 8.
The subtraction method involves subtracting successive numbers repeatedly.
Subtract the numbers 1,7,19,37,61,91,127,169,217,331,397……..successively till we get a zero.
Subtracting the successive number method is based on the properties of cubes and the differences between consecutive cubes. Here, the subtraction took place in 8 steps to reach zero. Hence, the cube root of 512 is 8.
