log(75)10-log(3)10+log(4)10
log(10000)/log(10)
-log10^(10^-3/2) 怎么写成log +log 或log-log的形式
化简2log`5(10)+log`3(0.25)+log`1/5(125)=
log
log(2)9×log(3)4
log(2)9log(3)4等于
log(27)16/log(3)4=
已知a大于b大于1,log(a)b+log(b)a=10/3,求log(a)b-log(b)a的值
已知a<b<1,log(a)b+log(b)a=10/3,求log(a)b-log(b)a的值
设a>b>1,log(a)b+log(b)a=10/3,则log(a)b-log(b)a=
log(log(10a))和log(log(100a))化简为多少
化简log(2)3 * log(3)4 * log(4)7 *log(7)16
