2log3 2等于多少
log32乘以[根号(2+根号三)-根号(2-根号三)] 32是底数

[3^(1/2)+1]^2=4+2(3)^(1/2),2+3^(1/2)=[3^(1/2)+1]^2/2,[2+3^(1/2)]^(1/2)=[3^(1/2)+1]/2^(1/2).[3^(1/2)-

根号2等于多少

根号2约等于1.4142135623730950488016887242097一般的话取1.414

求值:【log2(3)+log4(9)+log8(27)+log16(81)+log32(243)】—5log2(3/2

【log2(3)+log4(9)+log8(27)+log16(81)+log32(243)】-5log2(3/2)=【log2(3)+log2^2(3^2)+log2^3(3^3)+log2^4(3

(log43+log83)(log32+log92)=

解题思路:考查对数式的化简解题过程:varSWOC={};SWOC.tip=false;try{SWOCX2.OpenFile("http://dayi.prcedu.com/include/read

lg(-2)等于多少?lg2等于多少

lg(-2)无意义lg2=0.30102999566398119521373889472449再问:写错了...忘记打根号5了...是lg(-2+根号5)和lg(2+根号5再答:lg(-2+根号5)=

2+2等于多少?

2加上2等于4呢,

(log43+log83)(log32+log92)

(log43+log83)(log32+log92)=(log23/log24+log23/log28)(log32+log32/log39)=(log23/2+log23/3)(log32+log3

log32×log89过程 3和8是底数,2和9是真数

因为log89=log2^33^2=2/3log23,log32*log23=1那么,log32×log89=2/3
