log2 5/log2 3为什么等于log3 5 log2 5,log2 3的2是角标 log3 5的3是角标
log2(3)+log3(5)+log3(2)=?
log2(20)-log2(5)+2log3(2)×log4(3)
log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2[log
3/2,log3^5,log2^3的大小关系是
log3(5),log2(3),2/3的大小关系
我是这样做的log2(3)*log3(5)*log5(49)*log7(64)=log2(3)*log3(5)*2log
log2 3/log2 5等于log2 3-log2 5么?
计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15
(log2 5+log4 125)log3 2/ log根号3 5
log3/2乘以5log2/3怎么化简?
log3 2等于log2 3的x次方
log2 3×log3 7=log2 7
