## 最终结论
```python
def prod_Square(n):
    for i in range(int(n**0.5) + 1):
        for j in range(int(n**0.5) + 1):
            if (i**2) * (j**2) == n:
                return True
    return False

# Test cases
assert prod_Square(25) == False
assert prod_Square(30) == False
assert prod_Square(16) == True
