log3 2是大于还是小于log2 3
解不等式log3(x+2)大于0和log2(x-3)小于1,
解不等式log3(x+2)大于0和log2(x-3)小于1
log2(3)+log3(5)+log3(2)=?
3/2,log3^5,log2^3的大小关系是
(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7)
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)
2又8分之3是大于还是小于2.375?
log2(3)=a,log3(7)=b.log12(56)=log3(7*8)=log3(7)+3log3(2)
log2 3×log3 7=log2 7
log2 3 · log3 4 ·log4 5 ·log5 2 前面的是底数
