Analysis:

A = log & lt4 & gt{3},

B = log & lt5 & gt{3},

C = log & lt7 & gt{3}

All three are less than 1.

The same is true for real numbers. The larger the radix, the smaller the value.

Therefore,

Logs & lt4>{ 3}> Logs & lt5>{ 3}> Logs & lt7 & gt{3}

D = log<2>{ 5}> log<2 & gt{2}= 1

In a word, D>A & gtB& gt；; C
