计算log5(4)*log8(5)
高中数学对数计算求值(log2 125+log4 25+log8 5)*(log125 8+log25 4+log5 2
log3(2)*log5(3)*log8(5)
化简log3(4)*log4(5)*log5(8)*log8(9)的结果是?
[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
若log3^5 log5^7 log7^x=log4^2 log6^4 log8^6,求x=?
1.log2 3*log3 4*log4 5*log5 2 2.(log4 3+log8 3)8(log3 2+log9
1.log5的4次方*log8的5次方 2.lg35等于多少 3.化简log2的3次方*log27的125次方
(log4 3+log8 3)(log3 5+log9 5)(log5 2+log25 2)=
已知log8 9=m,log3 5=n,求log5 12
若log8(3)=a,log3(5)=b,试用a,b表示log5
