(log以2为底125的对数+log以4为底25+log8 5 )(log5 2 +log25 4+log125 8
高中数学对数计算求值(log2 125+log4 25+log8 5)*(log125 8+log25 4+log5 2
[log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2)]
[log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2)
(Log2 125+log4 25+log8 5)(log5 2+log25 4+log125
计算:(log以4为底3的对数+log以8为底3的对数)(log以3为底2的对数+log以9为底2的对数)- log以½
(log以2为底25的对数+log以2为底五分之一的对数)(log以5为底4的对数+log以5为底二分之一的对数)
log以2为底25的对数乘以log以3为底4的对数乘以log以5为底9的对数
log以2为底25的对数乘log以3为底4的对数乘log以5为底9的对数=?
log以2为底25的对数+log以3为底4的对数+log以5为底9的对数
(log以5为底根号2的对数×log以49为底81的对数)÷(log以25为底1/3的对数×log以7为底4的3次方根的
﹙log以2为底5的对数+log以4为底125的对数﹚乘以﹙log以3为底2的对数/log以根号3为底的5的对数﹚
化简(log以4为底3的对数+log以8为底3的对数)乘(log以3为底2的对数+log以9为底2的对数)
