log(2)2√2 减1怎么算?

log(2)2√2 减1怎么算? log(1/2)^5怎么算 (log(4)3+log(8)3)(log(3)2+log(9)2) 怎么个思路 ［『log(6)』的平方+『log(6)』的平方+2log(6)．log(6)］除以2log(6)怎么算啊! (log(4)3+log(8)3)(log(3)2+log(9)8) 怎么个思路 log(1/2)^8怎么解 log(10)(25/9)减log(10)(7/4)减log(10)(1/9)加1/2log(10)(49) 9^log(3)2^1/2具体步骤怎么算啊 log(2x)+log(3y)-log(2z) 怎么化简?log3(x^2-2x-6)=2 log(3x+6)=1+log(x)求解,求每步详...log(2x)+log(3y)-log(2z) 怎么化简?log3(x^2-2x-6)=2 log(3x+6)=1+log(x)求解, 对数的平方怎么算?log^5-log^2怎么算? [log(x)(25)]^2 就是对数函数外的平方怎么算?2log(x)(25)-3log(25)(x)=1 计算：（1） log(2)(3)*log(3)(4)*log(4)(5)（2）log(2)(7)*log(√7)(8) 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(2,a)/2 怎么化成log(4,a)RT log(4)y+log(2y)=9怎么解 计算:lg25+2lg2+2^1+log(2)(3) 主要log(2)(3)这个是怎么算的..计算:lg25+2lg2+2^1+log(2)(3) 主要log(2)(3)这个是怎么算的 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) (log下2上125+log下4上25+log下8上5)(log下5上2+log下25上4+log下25上8)怎么算
