(log2 27)×(log3 8)=?
(log2 3+log4 27)*(log3 4+log9 8)=log2的2是下标,后同
(log2 3+log4 27)(log3 4+log27 16)
log2(3)*log3(5)*log5(8)(具体步骤)
log5[log2(log3 9)]=
log3 根号27+lg25+lg4+7的log2幂+(-9.8)º= 由其是7的log2幂.
已知log2=a,log3=b;问log3(4) ()里的数为对数!
log2 49*log3 16*log7 27=?(空格后是真数)
比较大小 log2(3)log3(4)
证明不等式log2(3)>log3(4)
log2^9*log3^8
设p=log2(3)、Q=log2【log3(2)】、R=log2【log3(2)】,则它们的大小关系
log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2[log2(32)-log2(3÷4)+log2log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2【log2(32)-log2(3÷4)+log2(6)】=?lgx+lg(x+15)=2 ..X
log的平方(log3(log5x))=0 (lgx)的平方 +2lgx=8是log2(log3(log5x))=0
已知log(32)9=p,log(27)25=q,适用p,q表示lg5p=log32(9)=2/5×log2(3)=2/5×1/log3(2)∴log3(2)=2/5pq=log27(25)=2/3×log3(5)∴log3(5)=3q/2lg5=log3(5)/log3(10)=log3(5)/[log3(2)+log3(5)]=15pq/(4+15pq)结果怎么出来的?
log2(3)+log3(5)+log3(2)=?
已知log2(x)=3,则3 {1-log3(x)}=1-log3(x)是指数
设p=log2(3)、Q=log3(2)、R=log2【log3(2)】,则它们的大小关系
