2log以5为底10+log以5为底0.25 =log5(100*0.25)=2
lg45=lg9*5=2lg3*lg52=2lg3(1-lg2)= 0.6670
1. 2log以5为底10+log以5为底0.25
=log以5为底100+log以5为底0.25
=log以5为底25
=2
2. lg根号下45
=(lg45)/2
=(lg5+lg9)/2
=(1-lg2+2lg3)/2
=(1-0.3010+2×0.4771)/2
=0.9971

计算log以2为底25·log以3为底2√2·log以5为底9的结果为 .
计算:log以根号3为底2-log以3为底32/9+log以3为底8-25(log以5为底3)次方
log以8为底9＝a log以3为底5＝b 则log以10为底2＝ 用a,b表示
log以3为底[log以4为底（log以5为底a的对数）]=log以4为底[log以3为底（log以5为底b的对数）]=0,则a/b是?计算
log以5为底35+2log以为底根号二-log以5为底五十分之一-log以五为底14
log以2为底5为真数与log以5为底8
求(lg2)^2+lg2lg5+log(3)5/log(3)10值 注：log（3）5是log以3为底
log以5为底（3x-2)>log以5为底（x+1)
log以5为底3的对数×log以27为底125的对数
2log以5为底10的对数加log以5为底0.25的对数
log以1为底的(x-3)>log以3分之一底的5
计算log以2为底20的对数-log以2为底10的对数
