化简,log(5)35+2log(1/2)√2 - log(5)1/50 - log(5)14注意:括号里的为真数,(√2)这个是 根号2
化简,log(5)35+2log(1/2)√2 - log(5)1/50 - log(5)14
注意:括号里的为真数,(√2)这个是 根号2
化简,log(5)35+2log(1/2)√2 - log(5)1/50 - log(5)14注意:括号里的为真数,(√2)这个是 根号2
log(5)35+2log(1/2)√2 - log(5)1/50 - log(5)14
=log5(35÷1/50÷14)+2log(1/2)(2^1/2)
=log5(125)+2log(1/2)[(1/2)^-1/2]
=3log5(5)-2*(-1/2)log1/2(1/2)
=3+1
=4
log(5)35+2log(1/2)根号2-log(5)1/50-log(5)14 括号里的为log的底数
化简2log`5(10)+log`3(0.25)+log`1/5(125)=(2) log`2(根号2)+log`9(27)+(1/4)^log`4(1/16) 注意 `为下角标
化简1,log(√3)3√3 2,2log(5)10+log(5)0.25
计算:(1) log(2)(3)*log(3)(4)*log(4)(5)(2)log(2)(7)*log(√7)(8)
已知log(14)7=a log(14)5=b 用ab表示log(35)70=log(3)4*log(4)8*log(8)m=log(4)2 求m
化简,log(5)35+2log(1/2)√2 - log(5)1/50 - log(5)14注意:括号里的为真数,(√2)这个是 根号2
log(x+5)=log(x)+log(2) log(8)+log(x)=log(24) 2log(x)=log(2x)+log(3)
Log(2)1/25•log(3)1/8•log(5)1/9化简 还有已知log(18)9=a,log(18)5=b求log(36)45 值
(log(2)125+log(2)25+log(8)5)*(log(125)2+log(25)4+log(5)8)
[log(3)3^1/2]^2+log(0.25)1/4+9log5根号5-log(根号3)1=?
计算:1/[log(2)3]+1/[log(5)3]=?
log(0.1)log(0.2)log(0.5)(1/根号5次2)=x,求x的值
log(X+5)+log(X+2)=1
化简(log(2)(5)+log(4)(0.2))(log(5)(2)+log(25)(0.5))(还要追问,不懂的朋友请不要复制回答)
化简(log[4]3+log[8]3)×(log[3]2+log[9]2)如题
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
求值 log【9(下标)】3+log【 9(下标)】27 log【2】(1/2)- log【1/2】2
log(2)5=a,log(2)7=b用ab表示log(35)28
