9 is a perfect square because it can be expressed as 3 * 3 (the product of two equal integers). 16 16 is a perfect square because it can be expressed as 4 * 4 (the product of two equal integers). 25 25 is a per
- (a)81=9²,是完全平方数。- (b)18没有整数平方根(介于4²=16和5²=25之间),故不是完全平方数。- (c)100=10²,是完全平方数。- (d)121=11²,是完全平方数。第二个问题:答案(a)900是能同时被4、9、10整除的最小平方数。分析如下:...
