计算:log2(8)×log4(5)×log5(16)
高中数学对数计算求值(log2 125+log4 25+log8 5)*(log125 8+log25 4+log5 2
log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2[log
log2(3)*log3(4)*log4(5)*log5(6)*log6(7)*log7(8)=?
[log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2)]
[log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2)
