log(2)(25)×log(3)(1/16)×log(5)(1/9)=?
log(2)(25)×log(3)(1/16)×log(5)(1/9)=?
log(2)(25)×log(3)(1/16)×log(5)(1/9)=?
log(2)(25)×=lg25/lg2=2lg5/lg2 log(3)(1/16)=lg(1/16)/lg3=-4lg2/lg3 log(5)(1/9)=lg(1/9)/lg5=-2lg3/lg5 log(2)(25)×log(3)(1/16)×log(5)(1/9)=16
2^log(4)(3)加3^log(9)(1/4)加5^log(1/25)(2)
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(2)1/25•log(3)1/8•log(5)1/9化简 还有已知log(18)9=a,log(18)5=b求log(36)45 值
2log(5 ) 25+3log(2) 64-8log(2) 1 ( )内代表的是以什么为底
2log(5 ) 25+3log(2) 64-8log(2) 1 ( )内代表的是以什么为底
2log(5)25＋3log(2)64＝?
计算：1/[log(2)3]+1/[log(5)3]=?
log(3)1+log(2)根号2+lg1000
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
log(10)(25/9)减log(10)(7/4)减log(10)(1/9)加1/2log(10)(49)
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.
log(2)(25)*log(3)(根号2)*log(5)(9)+_+ 请问为什么错?
log（2）25×log（3）4×log （5）9等于多少?
log(1/2)3,log(1/3)3,log(1/4)3比大小
