log2 3乘log27 125
log2 3乘log27 125
log2 3乘log27 125
log2 5
log2 3*log27 125
(lg3/lg2)*(lg5^3/lg3^3)
lg5/lg2
log2 3乘log27 125
=log2 3乘log3 5
=log2 5
=(lg3/lg2)*(3lg5/3lg3)
=lg5/lg2
log2(3)*log27(125)
=(lg3/lg2)*(3lg5/3lg3)
=lg5/lg2
=log2(5)
log2 3乘log27 125
(log2 3+log4 27)(log3 4+log27 16)
1.log5的4次方*log8的5次方 2.lg35等于多少 3.化简log2的3次方*log27的125次方
x=log27(3^-2)=-2log27(3)=-2×(1/3)=-2/3 为什么是乘三分之一
log2 12÷log2 3+log3 9 -log27 64 (空格前面是底数后面是对数)
5^log5(2)-4^log2(3)+3^log27(8)等于多少?(1)5^log5(2) - 4^log2(3) + 3^log27(8)等于多少?(2)开更号[lg2 (1/3) - 4lg(3) + 4 + lg(6) - 2^(-1)]等于多少?
1.已知lg2=0.3010,求lg52.计算log2 3·log27 128注:log2 3 是2为低 3是真数
log2^3乘log3^2
1.log5为底的4的对数*log8为底的5的对数2.化简log2为底3的对数*log27为底125的对数
计算(1)log327+ lg 1002+ log21 (2)lg 5+lg 2+ log2 18-log2 9 (3)ln e 3 +2 log2 6 (4) log8 9×log27 32
lg2+lg5-log2(3)乘log3(2)
log8的9乘log27的32怎么做
log27^x=-2/3求x
[log2]2+log2乘log50+log25
x=log27(1/9),求x的值这个解法哪里错了?x=log27(3^-2)=-2log27(3)=-2×3=-6
log2 6-log2 3
log2^6-log2^3
log2(4)/log2(3)
