9+log√2 27)(log27 4+log3√3 8)
(log(2)125+log(2)25+log(8)5)*(log(125)2+log(25)4+log(5)8)
x=log27(3^-2)=-2log27(3)=-2×(1/3)=-2/3 为什么是乘三分之一
[log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2)
1.log3 3/log27 64 2.log8 9 log3 2
求:(log2 125+log4 25+log8 5)(log125 8+log25 4+log5 2);
log3^2*log5^7/log9^1/7*log125^8
(log(2)5+log(4)125)×log(3)2÷log(根号三)5
(log2^5+log4^125)(log3^2)/(log(根号3)^5 要具体的过程,
log2/27及 log 3=a log5=b
