化简(log3 4)/(log9 8)

化简(log3 4)/(log9 8) log3*2/log9*4 log3*2/log9*4=? (log2(3)+log8(9))x(log3(4)+log9(8)+log3(2)) 求（log2^3+log8^9)(log3^4+log9^8+log3^2)的值 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 (log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7)(log三次根号4 8) 化简(log4(3)+log8(3))(log3(2)+log9(2)) 计算log9底8分之log3底2 (log3^2 + log9^4)×(log4^3 + log8^3) 为什么log9 (9/2)=log3(81/4) 解log81(X)+log9(X)+log3(X) < 7/4 化简:log2 2+log5 1-3^(2log9 5)+(3log3 5)^2+3^log3 2 (log2 3+log8 9)(log3 4+log9 8+log3 2)的运算过程关于换底公式的都懂不起哟 计算题：（log2的次方+log8 9的立方）（log3 4的立方+log9 8的立方+log3 2的立方)过程图图图图图图图图 已知log3(4)=a,log3(5)=b 则log9(16/25)= 已知log3(4)=a,log3(5)=b 则log9(16/25)= （log2 3+log4 27）*（log3 4+log9 8）=log2的2是下标,后同
