log(760/50) = 1.1818435879448 这个具体怎么算出来的? 可以说log a x +log a y=log a log(a)M+log(a)N=? log(27)16/log(3)4= 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=? 函数y=log log(3)4*log(4)8*log(8)M =log(2)16 M是多少呃.... log log log 求等式log(2)3*log(3)4*log（4)5*log(5)6*log(6)7*log(7)m=log(3)9时m的值? matlab 极小化函数f（x,y) = -9*y - 10*z + 100*(-1*log(100-y-z)) - log(y) - log(z) - log(50-y+z)matlab怎么极小化这个函数,我搞的老是出错 log₂log₃log₄ X=log₃log₄log₂ Y=log₄log₂log₃ Z=0X+Y+Z=?为什么是71呀? log（x+5）=log（x）+log（2） log（8）+log（x）=log（24） 2log（x）=log(2x)+log(3) 求值：lg2/log（底数50）10+lg5/log（底数5）10=?lg2/log5010+lg5/log510=? 已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x+y的值 log(a)(b)=log(c)(b) /log(c)(a) 怎么证log(a)(b)=log(c)(b) /log(c)(a)怎么证 log(2)3=a,则log(6)4=（
