(log3 2)+log9 2)*(log4 3+log8 3)+(log3 3^1/2)^2+ln根号e-lg1
(log3 2)+log9 2)*(log4 3+log8 3)+(log3 3^1/2)^2+ln根号e-lg1
(log3 2)+log9 2)*(log4 3+log8 3)+(log3 3^1/2)^2+ln根号e-lg1
原式=(lg2/lg3+lg2/lg9)(lg3/lg4+lg3/lg8)+(1/2*log3(3))²+lne^1/2)-0
=(lg2/lg3+lg2/2lg3)(lg3/2lg2+lg3/3lg2)+(1/2)²+1/2lne
前面约分
=(1+1/2)(1/2+1/3)+1/4+1/2
=1
log3*2/log9*4
log3*2/log9*4=?
log3 5-log3 15+1/2log9 27 的值
急 求 (log3 2+log9 2)-(log4 3+log8 3)求 (log3 2+log9 2)-(log4 3+log8 3)
(log3 2)+log9 2)*(log4 3+log8 3)+(log3 3^1/2)^2+ln根号e-lg1
【(log4)^3+.(log8)^3】【.(log3)^2+.(log9)^2】=几啊
化简此式(log4 3+log8 3)×(log3 2+log9 2)
为什么log9(2)=log3(2)/2如题
数学指对数方程.1.【log3(x)】平方+log9(3x)=2
已知Log9(8)=a,则Log3(2)=?用a表示
(log3 2+log9 2)*(log4 3+log8 3)求值
化简(log4(3)+log8(3))(log3(2)+log9(2))
(log3^2 + log9^4)×(log4^3 + log8^3)
|log3(5)-2|+log9(25)+(1/32)^1/5
计算log9底8分之log3底2
为什么log9 (9/2)=log3(81/4)
求值:(log4^ 3+log8 ^9)*(log3^ 2+log9 ^16)
log 243÷log9 =log3^5÷log3^2 =log3^5-log3^2 然后怎么写
