In this post, I have covered every step with images and at the end you will get examples as well as practice problems with answer.

Q.1 Find the cube root of 512 using the prime factorization method.

Solution:

Using factorization method ,find the prime factor of 512

512= 2×2×2×2×2×2×2×2×2

Make triplets of prime factors

512= 2×2×2× 2×2×2× 2×2×2

3√512=3√2×2×2× 2×2×2× 2×2×2

3√512=2×2×2

3√512=8

Hence ,cube root of 512 is 8

15625= 5 × 5 ×5 ×5 ×5 ×5

Make triplets of prime factors

3√15625=3√5 × 5 ×5 ×5 ×5 ×5

3√15625=5×5×5

3√15625=125

Hence , cube root of 15625 is 125 .

Q.3 Find the cube root of 27000 using the prime factorization method.

Solution:

Using factorization method ,find prime factors of 27000

27000= 2×2×2×3×3×3×5×5×5

3√27000=3√2×2×2×3×3×3×5×5×5

3√27000=2×3×5

3√27000=30

Hence ,cube root of 27000 is 30

Q.4 Find the cube root of 110592 using the prime factorization method.

Solution:

Using factorization method ,find prime factor of 110592

110592= 2×2×2×2×2×2×2×2×2×2×2×2×3×3×3

3√110592=3√2×2×2×2×2×2×2×2×2×2×2×2×3×3×3

3√110592= 2×2×2×2×3

3√110592=48

Hence , cube root of 110592 is 48 .
