Comparison of cube roots: Which is greater, ∛8 or ∛1000?

Difficulty: Easy

Correct Answer: ∛1000

Explanation:

Introduction / Context: Estimating cube roots of perfect cubes is straightforward and useful in quick comparisons.

Given Data / Assumptions: Compare ∛8 and ∛1000.

Concept / Approach: Recognize that 8 = 2^3 and 1000 = 10^3. Then cube roots are exact integers.

Step-by-Step Solution: ∛8 = 2.∛1000 = 10.Therefore, ∛1000 > ∛8.

Verification / Alternative check: Obvious by comparing 2 and 10.

Why Other Options Are Wrong: ∛8 is smaller; equality does not hold.

Common Pitfalls: Confusing square roots with cube roots.

Final Answer: ∛1000
