log2(5)*log5(8)化简

log2(5)*log5(8)化简 比较大小log2 5和log5 8 计算：log2(8)×log4(5)×log5(16) log2(5) ×log5(8)=3步骤 (log2^5+log4^0.2)(log5^2+log25^0.25)化简 比较log2底5与log5底8的大小 log2(3)*log3(5)*log5(8)（具体步骤） log2 5乘log5 4等于多少 log2^5乘以log5^2等于多少? lg8*log2(5)*log5(4)得多少? (log5(10))^3-(log5(2))^3-3log5(10)*log2(5) lg(1/4)-lg2(5) 2log5(10)+log5(0.25) 2log2(25)-3log2(64) log2(log2(16) ) [log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2)][log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2) 计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15 化简:log2 2+log5 1-3^(2log9 5)+(3log3 5)^2+3^log3 2 log2(3)*log3(4)*log4(5)*log5(6)*log6(7)*log7(8)=? [log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2) log7（1/8) * (log8 （25）+log2 （5）)* log5 （49） 怎么求
