Question 1: Find the cube root of 64.

Solution:

To find the cube root of 64, we use prime factorization: 64 = 2 × 2 × 2 × 2 × 2 × 2 = (2 × 2 × 2) × (2 × 2 × 2) So, ³√64 = ³√(2³ × 2³) = 2 × 2 = 4

Question 2: Find the cube root of 343.

Solution:

To find the cube root of 343, we use prime factorization: 343 = 7 × 7 × 7 = 7³ So, ³√343 = ³√(7³) = 7

Question 3: Find the cube root of 729.

Solution:

To find the cube root of 729, we use prime factorization: 729 = 3 × 3 × 3 × 3 × 3 × 3 = (3 × 3 × 3) × (3 × 3 × 3) So, ³√729 = ³√(3³ × 3³) = 3 × 3 = 9

Question 4: Find the cube root of 1728.

Solution:

To find the cube root of 1728, we use prime factorization: 1728 = 2 × 2 × 2 × 2 × 2 × 2 × 3 × 3 × 3 = (2 × 2 × 2) × (2 × 2 × 2) × (3 × 3 × 3) So, ³√1728 = ³√(2³ × 2³ × 3³) = 2 × 2 × 3 = 12

Question 5: Find the cube root of 9261.

Solution:

To find the cube root of 9261, we use prime factorization: 9261 = 3 × 3 × 3 × 7 × 7 × 7 = (3 × 3 × 3) × (7 × 7 × 7) So, ³√9261 = ³√(3³ × 7³) = 3 × 7 = 21

Question 6: Find the cube root of 4096.

Solution:

To find the cube root of 4096, we use prime factorization: 4096 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 = (2 × 2 × 2 × 2) × (2 × 2 × 2 × 2) × (2 × 2 × 2 × 2) So, ³√4096 = ³√(2⁴ × 2⁴ × 2⁴) = 2 × 2 × 2 = 16

Question 7: Find the cube root of 8000.

Solution:

To find the cube root of 8000, we use prime factorization: 8000 = 2 × 2 × 2 × 2 × 2 × 2 × 5 × 5 × 5 = (2 × 2 × 2) × (2 × 2 × 2) × (5 × 5 × 5) So, ³√8000 = ³√(2³ × 2³ × 5³) = 2 × 2 × 5 = 20

Question 8: Find the cube root of 3375.

Solution:

To find the cube root of 3375, we use prime factorization: 3375 = 3 × 3 × 3 × 5 × 5 × 5 = (3 × 3 × 3) × (5 × 5 × 5) So, ³√3375 = ³√(3³ × 5³) = 3 × 5 = 15

Question 9: Find the cube root of -216.

Solution:

To find the cube root of -216, we use prime factorization: -216 = -(2 × 2 × 2 × 3 × 3 × 3) = -(2 × 2 × 2) × (3 × 3 × 3) So, ³√-216 = ³√[-(2³ × 3³)] = -(2 × 3) = -6

Question 10: Find the cube root of -512.

Solution:

To find the cube root of -512, we use prime factorization: -512 = -(2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2) = -(2³ × 2³ × 2³) So, ³√-512 = ³√[-(2³ × 2³ × 2³)] = -2

Question 11: Find the cube root of -1331.

Solution:

To find the cube root of -1331, we use prime factorization: -1331 = -(11 × 11 × 11) = -11³ So, ³√-1331 = ³√[-(11³)] = -11

Question 12: Find the cube root of -27/64.

Solution:

To find the cube root of -27/64, we use prime factorization: -27/64 = -(3 × 3 × 3) / (4 × 4 × 4) = -(3³) / (4³) So, ³√(-27/64) = ³√[-(3³) / (4³)] = -3/4

Question 13: Find the cube root of -125/216.

Solution:

To find the cube root of -125/216, we use prime factorization: -125/216 = -(5 × 5 × 5) / (6 × 6 × 6) = -(5³) / (6³) So, ³√(-125/216) = ³√[-(5³) / (6³)] = -5/6

Question 14: Find the cube root of -27/225.

Solution:

To find the cube root of -27/225, we use prime factorization: -27/225 = -(3 × 3 × 3) / (15 × 15 × 15) = -(3³) / (15³) So, ³√(-27/225) = ³√[-(3³) / (15³)] = -3/15 = -1/5

Question 15: Find the cube root of -64/343.

Solution:

To find the cube root of -64/343, we use prime factorization: -64/343 = -(4 × 4 × 4) / (7 × 7 × 7) = -(4³) / (7³) So, ³√(-64/343) = ³√[-(4³) / (7³)] = -4/7

Question 16: Find the cube root of 64 * 729.

Solution:

To find the cube root of 64 * 729, we use prime factorization: 64 = 2 × 2 × 2 × 2 × 2 × 2 = (2³) × (2³) 729 = 3 × 3 × 3 × 3 × 3 × 3 = (3³) × (3³) So, 64 * 729 = (2³) × (2³) × (3³) × (3³) ³√(64 * 729) = ³√[(2³) × (2³) × (3³) × (3³)] = 2 × 2 × 3 × 3 = 36
