log2(3)*log3(4)*.log15(16)

(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7)(log三次根号4 8) [log3（4）+log根下3（2）][log2(9)+log4(根3)] (log2 5+log4 125)log3 2/ log根号3 5 log2(3)*log3(4)*log4(5)*.log(k+1)(k+2)=log2(k+2) 怎么证 求值(log43+log83)(log32+log92) 注：log后面那为数是底数=5/6*log3/log2*3/2*log2/log3=5/4 怎么来的 log的计算 ：log2（20）-log4（25)= log3(2)×log2（5）×log5（3）=?log2[log2(32)-log2(3÷4）+log2log的计算 ：log2（20）-log4（25)= log3(2)×log2（5）×log5（3）=?log2【log2(32)-log2(3÷4）+log2（6）】=?lgx+lg（x+15）=2 ..X log2^3*log3^4怎么算 比较大小 log2（3）log3(4) 证明不等式log2（3）>log3(4) log2(3)*log3(4)*.log15(16) (log3^4+log5^2)(log2^9+log2^根号3) log2 20---log2 5+log3 4 * log4 3 等于什么 已知log（32）9=p,log（27）25=q,适用p,q表示lg5p=log32(9)=2/5×log2(3)=2/5×1/log3(2)∴log3(2)=2/5pq=log27(25)=2/3×log3(5)∴log3(5)=3q/2lg5=log3(5)/log3(10)=log3(5)/[log3(2)+log3(5)]=15pq/(4+15pq)结果怎么出来的? 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 log2(1/2)+2的log1/2(3)+log3(2)乘以log(3)= (log2(5）+log4（125））×log3（2）/log根号3（5） (log2^5+log4^125)(log3^2)/(log(根号3)^5 要具体的过程, (log2(5)+log4(125))(log3(2)/log√3(5))怎么解?
