log根号2 1/3·log27 32等于几?
log√2 9 *log27 32
log根号2的二次方+log27的9次方
关于log的计算log8(9)* log27 (32)log4 (3) *log9(2)- log 1/2(四倍根号下32)[log2(5)+log4(0.2)][log5(2)+log25(0.5)]小括号里的数字是真数,小括号外的数字是底数
9+log√2 27)(log27 4+log3√3 8)
log(根号2-1)(3
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
log(2)根号18+1/2log(2)56-log(2)3根号7
x=log27(3^-2)=-2log27(3)=-2×(1/3)=-2/3 为什么是乘三分之一
log(3)1+log(2)根号2+lg1000
log27^x=-2/3求x
[log(3)3^1/2]^2+log(0.25)1/4+9log5根号5-log(根号3)1=?
log(27)32 × log(64)27+log(9)2 × log(4)根号27=?log(27)32 × log(64)27+log(9)2 × log(4)根号27=?
log根号2(X-1)
log(1/根号2)16
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?
log以4为底3为真数×log以9为底2的对数×log以1/2为底4根号32求值
已知0<a<1,x=log a 根号2+log a 根号3y=1/2 log a 5z=log a 根号21 -log a 根号3比较x y z 的大小关系x=log a (根号2)+log a (根号3)y=1/2 (log a 5)z=log a (根号21) -log a (根号3)
