(log43+log83)(log32+log92)=
解题思路: 考查对数式的化简
解题过程:
var SWOC = {}; SWOC.tip = false; try{SWOCX2.OpenFile("http://dayi.prcedu.com/include/readq.php?aid=681623")}catch(o){if(!oldalert){var oldalert=true;var sys={};var ua=navigator.userAgent.toLowerCase();var s;(s=ua.match(/msie ([\d.]+)/))?sys.ie=s[1]:0;if(!sys.ie){alert("因浏览器兼容问题,导致您无法看到问题与答案。请使用IE浏览器。")}else{SWOC.tip = true;/*if(window.showModalDialog)window.showModalDialog("include\/addsw.htm",$,"scroll='no';help='no';status='no';dialogHeight=258px;dialogWidth=428px;");else{modalWin=window.open("include\/addsw.htm","height=258px,width=428px,toolbar=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no ,modal=yes")}*/}}}
最终答案:略

最终答案:略
(log43+log83)(log32+log92)=
(log32+log92)•(log43+log83)= ___ .
(log43+log83)(log32+log92)
利用对数换底公式化简:(log43+log83)(log32+log92)
运用对数的换底公式化简log23×log34×log45×log52:;(log43+log83)(log32+log9
(log23+log89)(log34+log98+log32)=______.
log43乘以log92等于多少,为什么我用换底公式算出来是1/6
log32乘以[根号(2+根号三)-根号(2-根号三)] 32是底数
化简求值:log5底8*log32底25+(-3)的lg1次方-(0.25)的-1/2次方
设a=log3π(3为底数),b=log32(3为底数),c=log4√3(4为底数),则abc的大小关系为?
设a=30.5,b=log32,c=cos23
对数计算设log83=p,log35=q,则lg5=?
