对数:log(4)8-log(1/9)3求值对数:log(4)8-log(1/9)3求值对数:log(4)8-log(1/9)3求值log(4)8-log(1/9)3=lg8/lg4-lg3/lg1/
对数:log(4)8-log(1/9)3 求值
对数:log(4)8-log(1/9)3 求值
对数:log(4)8-log(1/9)3 求值
log(4)8-log(1/9)3
=lg8/lg4-lg3/lg1/9
=lg2×4/2lg2-lg3/(-2×lg3)
=4/2+1/2
=5/2
对数:log(4)8-log(1/9)3 求值
对数计算1.{log(4)(3)+ log(8) (3)} X {log(3)(2)+log(9)(2)}2.{log(2)(3)} X {log(3)(4)+log(9)(2)}3.(lg2)^+1g2X 1g5 +1g50
[log(4)3+log(8)3][log(3)2+log(9)2]-log(1/2)32∧1/4过程详细点,log(4)3是log以4为底3的对数,
log以4为底8的对数-log以9分之1为底3的对数-log以根号2为底4的对数
log以9为底4的对数+ log以3为底8的对数除以log以1/3为底16的对数
有关对数的计算题(log(4)3+log(8)3)(log(3)2+log(9)2)=?
【高一数学化简对数函数》》》】化简log(3)4*log(4)5*log(5)8*log(8)9( )是底数
高一函数【运算对数】运算:(log【2】3-log【4】27)×(log【3】4+log【9】8)【 】内的是底数.
这道对数题怎么解[log(4)3+log(8)3]*[log(3)2+log(9)2]小括号里是底数.
问道数学题(高一)(对数)化简:(log 3 + log 3)(log 2 + log 2) 4 8 3 9有些过程,拜托了.
(log以4为底3的对数+log以8为底3的对数)*(log以3为底2的对数+log以9为底2的对数)计算题
化简(log以4为底3的对数+log以8为底3的对数)乘(log以3为底2的对数+log以9为底2的对数)
log以3为底的4的对数/log以9为底的8的对数=?
log的底数8对数9,乘以log的底数3对数32 等于?
