log2底2分之3与log3底2哪个大?
log2 (3)和log3 (2)哪个大?log3 (4) 和log2 (3)呢
log2(3)+log3(5)+log3(2)=?
log3^2与log2^3比较大小及原因
(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7)
利用换底公式求值:1.log2 25 ×log3 4 ×log5 9 2.(log4 3+log8 3)(log3 2+
lg2+lg5-log2(3)乘log3(2)
log2(20)-log2(5)+2log3(2)×log4(3)
(log3^4+log5^2)(log2^9+log2^根号3)
log2(根号3)和log3(根号2)哪个大有判断方法吗
比较log2 √2与log2 √3,log3 2与1,log1\3 4与0的大小
运用对数换底公式化简log2(3)*log3(4)*log4(5)*log5(2),
log2(3)=a,log3(7)=b.log12(56)=log3(7*8)=log3(7)+3log3(2)
