35、N是正整数，N是否为一个整数的平方？

    

（1）4N是一个整数的平方；

    

（2）N^3是一个整数的平方；

    

 

    

【答案】D

    

【思路】

    

（1）K为整数，4N=k^2=2^2*N,说明N肯定是个完全平方。

    

（2）N^3=K^2，N必须是一个整数的平方

    

9、If n=p/q，and both of p and q are non-zero
integers, is n an integer?

    

(1) n^2 is an
integer;

    

(2) n^3 is an
integer;

    

 

    

【答案】D

    

【思路】主要考虑到这样的数字,如:通过条件一N可能为根号2, 可是根号2是无限不循环小数,是无法用分数表示的.只有循环小数和分数都是有理数,可以互相转化.

    
大家谁作这样的题有撬门赶紧分享下，每次我看见，都像身体过了电，脑袋马上变成动物的
brain earthquake 简直！！！

每天分析、总结SC当然好，速度非常慢也是正常，但别忘了还是每天要至少一个section大全的保持做题的感觉、掐时间做题。你可能都记住答案了，没关系，这次重点关注每个选项为什么是错误的，你会发现时间可能还会不够呢。
