Answer:
One of the prime factors (3) has an odd power hence 768 is not a perfect square. Since the powers of the prime factors are even then 1296 is a perfect square. Since one of its prime factors has an odd power then 8000 is not a perfect square. Since both prime factors have an even power then 9025 is a perfect square.
