本文介绍了证明以下每个项的g(n)为O(g(n))的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
2 ^(sqrt(log(n))是 O(n(^ 4/3))
n ^(4/3)是 O (n(log(n))^ 3)
n(log(n))^ 3)是 O(n ^(log(n))
n ^(log(n))是 O(2 ^ n)
当他们有相同的基础时,我可以为他们做;当他们没有相同的基础时,我无法弄清楚-我知道这些都是真的。
I can do it for them when they have the same base; I can't figure it out when they don't have the same base--I know that these are all true.
推荐答案对双方进行日志记录,这是允许的,因为log是单调递增的函数
Take log on both sides, for each of them. This is permitted because log is a monotonically increasing function
