求值.(log3^2+log9^3)*(log4^3+log8^3)+(log3^3^1/2)^2+ln根号下e-lg1我实在是算不好了,要命啊急滴,
题目请描述规范、准确.如,log3^2应该是log9,而不是(log3)^2吧?那么log3^3^1/2是不是log[27^(1/2)]?还有ln根号下e-lg1,指的是ln[(e-lg1)^(1/2)]呢,还是ln[e^(1/2)]-lg1?不说清楚结果是不一样的.
(log3 2+log9 2)*(log4 3+log8 3)求值
求值:(log4^ 3+log8 ^9)*(log3^ 2+log9 ^16)
求值(log3(2)+log9(2))*(log4(3)+log8(3))打括号是真数.
log3*2/log9*4
化简log2[log3(log5 125)]……1.化简log2[log3(log5 125)]2.5log2(log9 81)3.log9 4 +log3 8 /log1/3 164.求值(lg2)^2+两个2*lg5+lg503.log9 4 +log3 8除以log三分之一 16 4.求值(lg2)平方+lg2乘以lg5+lg50

利用换底公式求值:1.log2 25 ×log3 4 ×log5 9 2.(log4 3+log8 3)(log3 2+log9 2)
log3*2/log9*4=?
化简(log4(3)+log8(3))(log3(2)+log9(2))
(log3^2 + log9^4)×(log4^3 + log8^3)
化简:log2 2+log5 1-3^(2log9 5)+(3log3 5)^2+3^log3 2
(log2(3)+log8(9))x(log3(4)+log9(8)+log3(2))
求(log2^3+log8^9)(log3^4+log9^8+log3^2)的值
log3 5-log3 15+1/2log9 27 的值
求x,y值.6log9^x+3log27^y=8log3^x+2log9^y=2
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
log3^2*log5^7/log9^1/7*log125^82.log2^3=1-a/a,则log3^12=
