log(1/4)(8/7) 和log（1/5）（6/5）大小

log(1/4)(8/7) 和log（1/5）（6/5）大小 计算：（1） log(2)(3)*log(3)(4)*log(4)(5)（2）log(2)(7)*log(√7)(8) 对数:log(4)8－log(1/9)3 求值 log(10)(25/9)减log(10)(7/4)减log(10)(1/9)加1/2log(10)(49) 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 log(1/8)X [log(4)3+log(8)3][log(3)2+log(9)2]-log(1/2)32∧1/4过程详细点,log(4)3是log以4为底3的对数， 对数计算1.{log(4)（3）+ log(8) (3)} X {log(3)(2)+log(9)(2)}2.{log(2)(3)} X {log(3)(4)+log(9)(2)}3.(lg2)^+1g2X 1g5 +1g50 1、若lg2=a,lg3=b,则lg√15=?（用a、b表达）2、若log(15)(5)=m,则log(15)(3)=(用m表示)3、log(2)(3)*log(3)(4)*log(4)(5)*log(5)(6)*log(6)(7)*log(7)(8）=?4、设log(3)(2)=log(2)(3^x),x=?这个对数函数我学的很不好,所以希望过 lg(7*2^x+8)>=log(√10) 2^x,求函数f(x)=log(1/2)x*log(1/2)x/4的最小值 已知lg2=0.301,lg3=0.477,求（1）log(2)1000,(2)log(5)0.5,(3)log(9)8,(4)log(1/2)1/3 试解关于x的不等式log(2)x+4log(3)x+12log(8)x+n·2^(n-1)·log(2^n)x log以1／4为底8／7的对数和log以1／5为底6／5的对数哪个大? [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 计算：8^(1-log(83))(27^(2/3))-log(32) 请问1/log(36)4等于log(4)36吗? (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. 比较log以1/4 8/7的对数与log以1/5 6/5对数的大小
