(log2(5)+log4(125))(log3(2)/log√3(5))怎么解?

(log2(5)+log4(125))(log3(2)/log√3(5))怎么解? (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根号3（5） log2(3)*log3(4)*log4(5)*.log(k+1)(k+2)=log2(k+2) 怎么证 log的计算 ：log2（20）-log4（25)= log3(2)×log2（5）×log5（3）=?log2[log log2(20)-log2(5)+2log3(2)×log4(3) log 2 3 * log3 4 * log4 5 *log5 2 化简 1.log2 3*log3 4*log4 5*log5 2 2.(log4 3+log8 3)8(log3 2+log9 [log3（4）+log根下3（2）][log2(9)+log4(根3)] Log2真数3*Log3真数4*Log4真数5*Log5真数2 怎么利用换底公式简化 运用对数换底公式化简log2(3)*log3(4)*log4(5)*log5(2),
