We have 400=2×2×2×2×5×5Grouping the prime factors of 400 into triples , factors2 and 5 are left overas ungrouped factor.So, 400 is not a perfect cube. 2. We have 3375=3×3×3×5×5×5Grouping the prime factors of 3375 into triples , no factor is left overSo, 3375 is a perfect cube.3. We have 8000=2×2×2×2×2×2×5×5×5Grouping the prime factors of 8000 into triples , no factor is left overSo, 8000 is a perfect cube. Similarly try other. Regards 3 View Full Answer
