关于2-HEIGHT

redli

(53) Ds 2-HEIGHT被定义为：X的最大因子2^N 的N, K 和M都是政整数，
问K的2-HEIGHT是否大于M的2-HEIGHT
i). K>M
ii).K/M为一个偶数
偶选B
[确认]B
[思路]i) 反例：K=3, M=2 ,ii) K的2-HEIGHT至少比M的2-HEIGHT大一

问题:我还是没明白2-HEIGHT指什么?

abelianrose

for examples:

8=2^3  =>
2-HEIGHT of 8 is 3

9=2^0*3^2=> 9 has 2-height 0  ( maybe you can define 3- height by your self, it will be 2 )

100= 2^2*5^2
100 has 2- height 2

it is the positive power of the 2 in the factorization expression of that number.

Y,I see, thank you so much!
