2log(2)根号30-log(2)3-log(2)5 求值
log(2)(25)*log(3)(根号2)*log(5)(9)
log(根号3+根号2) (根号3-根号2) 求值.
[log(5)√2·log(49)81]/[log(25)(1/3)·log(7)三倍根号四]
log(2)根号18+1/2log(2)56-log(2)3根号7
1.求值25^log(5)^3+lg100+log(1/2)4.
[log(3)3^1/2]^2+log(0.25)1/4+9log5根号5-log(根号3)1=?
(log(2)125+log(2)25+log(8)5)*(log(125)2+log(25)4+log(5)8)
计算log(2) 81/log(2) 3
log(2)9×log(3)4
log(2)9log(3)4等于
2的1-log(4)5次方+log(根号2)4+log(3)1/9的值?
计算题(log)已知log底数5 ^2=a,log底数5 ^3=b求log底数5根号54 的值
