Answer 2

Answer:

answer is -30

Step-by-step explanation:

resolving 27000 into prime factors we get

2×2×2×3×3×3×5×5×5

grouping the factors in triplets of equal factors we get

{2×2×2} × {3×3×3} × {5×5×5}

we find that the prime factors of 27000 can be grouped into triplets of equal factors and no factor left over. therefore 27000 is a perfect cube.

to determine the number whose cube is 27000, we collect one factor from each group

taking one factor from each triple we obtain

2×3×5=30
