Let’s extract and solve the square roots of the given numbers from the balloons:

1. $\sqrt{64}$

   • $\sqrt{64} = 8$

2. $\sqrt{361}$

   • $\sqrt{361} = 19$

3. $\sqrt{625}$

   • $\sqrt{625} = 25$

4. $\sqrt{900}$

   • $\sqrt{900} = 30$

5. $\sqrt{3600}$

   • $\sqrt{3600} = 60$

6. $\sqrt{256}$

   • $\sqrt{256} = 16$

7. $\sqrt{2500}$

   • $\sqrt{2500} = 50$

These are the positive integers that are the square roots of the numbers in the balloons.
