logС27 1/81

logС27 1/81 计算：8^(1-log(83))(27^(2/3))-log(32) 求值 log【9(下标)】3+log【 9（下标）】27 log【2】（1/2）- log【1/2】2 log∨6 (64)*log∨4 (1/27)*log∨3( 36) log∨6 (64)*log∨4 (1/27)*log∨3( 36) 1、log下标3 2(log下标4 3+log下标8 3)2、log下标1/3 √27+log下标27 1/3 1.求值log(2)27/log(8)9=____________.2.求值log(1/81)27=_____________.3.若log(64)x=-2/3,求x的值. log(2)5×log(5)81×log(3)4＋In√e.还有(log(2)3＋log(4)9)(log(3)4＋1／2log(3)2) 化简2log`5(10)+log`3(0.25）+log`1/5(125)=(2) log`2(根号2）+log`9(27）+（1/4)^log`4(1/16) 注意 `为下角标 log小2(1/49)*log小3（1/16）*log小7（1/27） log∨6 (64)*log∨4 (1/27)*log∨3( 36) 并写出解题思路 27-1/ 若a>0,b>0,a*b>1,log(1/2)[a]=ln2,则log(a)[b]与log(1/2)[a]的关系是：（）?(A)log(a)b< log(1/2)[a](B)log(a)b= log(1/2)[a](C)log(a)b>log(1/2)[a](D)log(a)b与log(1/2)[a] 无法比较大小我做到一半就做不下去了：a=(1/2)^(ln2)log [1 log(9544.5) log(0.84) log(34403.8) log(255);1 log(7183) log(0.31) log(5269) log(435);1 log(11144) log(0.06) log(4299) log(770);1 log(6618) log(0.12) log(16468) log(963);1 log(6353) log(0.07) log(2050) log(1473)]求以上矩阵逆矩阵,麻烦给 log(27)32 × log(64)27+log(9)2 × log(4)根号27=?log(27)32 × log(64)27+log(9)2 × log(4)根号27=? log(27)16/log(3)4= 1.求值25^log(5)^3+lg100+log(1/2)4.2.9^log(3)^5的值为（ ）.A.5 B.15 C.25 D.453.计算log(2)2+log(5)1-log(1/3)1/27+[3^log(3)5]^2+3^log(3)2.
