Answer:

Step-by-step explanation:

resolving 256 into prime factors we have

256 = 2×2×2×2×2×2×2×2

grouping the factors into triplets of equal factors we get

256= {2×2×2} × {2×2×2} × 2×2

clearly in grouping the factors in triplets of equal factor we are left with two factors 2×2

Therefore, 256 is not a perfect square.
