答案是0吧、
首先、化简一些单个的给你:
log9(这括号代表下标、下同)3=log3()3/log3()9=1/2
log9()27=log9()3*3次方=3log9()3=3/2
log2()1/2=log2()1-log2()2=0-1=-1
log1/2()2=1/log2()1/2=-1
接下来就简单勒、
原式=1/2+3/2*(-1)-(-1)
=1/2-3/2+1
=0
纯手办勿抄袭、求最佳、
化简 log 9(9是下标)3+log 9(9是下标)27 log2(2是下标)(1/2)-log1/2(1/2是下标)2化简 log 9(9是下标)3+log 9(9是下标)27 log2(2是下标)(1/2)-log1/2(1/2是下标)2
求值 log【9(下标)】3+log【 9(下标)】27 log【2】(1/2)- log【1/2】2
化简 log 9(9是下标)3+log 9(9是下标)27 log2(2是下标)(1/2)-log1/2(1/2是下标)2
已知log 16 3=a,log 9 16=?用a表示 (16和9是下标) 已知log18 2=a,log 3 2=?用a表示(18和3是下标)
化简(log[4]3+log[8]3)×(log[3]2+log[9]2)如题
化简:(log^3 2+log^9 2)(log^4 3+log^8 3)
log下标(1/3)=2log下标2x,求x.
log下标2 3乘以log下标3 4
1、log下标3 2(log下标4 3+log下标8 3)2、log下标1/3 √27+log下标27 1/3
【高一数学化简对数函数》》》】化简log(3)4*log(4)5*log(5)8*log(8)9( )是底数
(log(2)9+log(4)1/9)乘以(log(3)2+log(9)0.5) 括号里是底数.计算这道题.
高一函数【运算对数】运算:(log【2】3-log【4】27)×(log【3】4+log【9】8)【 】内的是底数.
(log(3)2+log(9)2)*(log(4)3+log(8)3) 带括号的是底数
化简2log`5(10)+log`3(0.25)+log`1/5(125)=(2) log`2(根号2)+log`9(27)+(1/4)^log`4(1/16) 注意 `为下角标
(log(8)9)/log(2)3
求值 log(2)9×log(3)2
log(2)9log(3)4等于
log(2)9×log(3)4
