(2log(2)3+1)/(2-log(2)3)怎么化简(2log(2)3+1)/(2-log(2)3)怎么化简(2log(2)3+1)/(2-log(2)3)怎么化简分子=2lg3/lg2+1=(2
(2log(2)3+1)/(2-log(2)3)怎么化简
(2log(2)3+1)/(2-log(2)3)怎么化简
(2log(2)3+1)/(2-log(2)3)怎么化简
分子=2lg3/lg2+1=(2lg3+lg2)/lg2=(lg9+lg2)/lg2=lg18/lg2
分母=2-lg3/lg2=(2lg2-lg3)/lg2=(lg4-lg3)/lg2=lg(4/3)/lg2
所以
原式＝(lg18/lg2 )/(lg(4/3)/lg2)
=lg18/lg(4/3)
像把假分数化成真整数加真分数的方法，把log(2)3看作一个整体，用分子除以分母，-2+5/(2-log(2)3)
(3log3 5)^2=5^2=25 3^log3 2=2 log2 2+log5 1-3^(2log9 5)+(3log3 5)^2+3^log3 2=23
log(2)9log(3)4等于
log(2)9×log(3)4
4^[log(2)3+log(4)8]
log(3)1+log(2)根号2+lg1000
计算：1/[log(2)3]+1/[log(5)3]=?
比较log(1/2)0.3,log(3)0.2的大小
计算：8^(1-log(83))(27^(2/3))-log(32)
log(根号2-1)(3
求值 log【9(下标)】3+log【 9（下标）】27 log【2】（1/2）- log【1/2】2
(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.
64^1/3-(-2/3)^0+log(2)8+(log(8)9)/(log(2)3)
log(2)根号18+1/2log(2)56-log(2)3根号7
2^log(4)(3)加3^log(9)(1/4)加5^log(1/25)(2)
log(1/2)3,log(1/3)3,log(1/4)3比大小
log(2)1/25乘以log(3)1/8乘以log(5)1/9
log(2)(25)×log(3)(1/16)×log(5)(1/9)=?
log a 2/3
log a(2/3)
