Hi, all, i am stuck with a DS problem and hope anyone can give me some feedbacks, thanks.:
23. If n is an integer between 2 and 100 and if n is also the square of an integer, what is the value of n?
(1) n is the cube of an integer.
(2) n is even.
the solution is A , but i don't get it.
我也在练习中,所以我说我的想法,有误的话请指较。
题目已有的条件为:n is an integer between 2 and 100 and if n is also the square of an integer
所以可以推数字必定落在这个范围中
2*2=4
3*3=9
4*4=16
5*5=25
6*6=36
7*7=49
8*8=64
9*9=81
10*10=100
(A)选项条件,n is the cube of an integer.一样类推
2*2*2=8
3*3*3=27
4*4*4=64
Thank you very much, appreciated it.
不错,思路很妙!
