1/log2 (11) +1 /log3(11)+1/log4(11)+1/log5(11)
1/log2 (11) +1 /log3(11)+1/log4(11)+1/log5(11)
设P=1/log2^11(底数为2的意思)+1/log3^11+1/log4^11+1/log5^11求p的取值范围
2007*log5(1)+log4(27)*log3(4)
log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2[log
求下列各式的值 1)log2 6+log2 3 2)lg5+lg2 3)log5 3+log5 三分之一 4)log3
利用换底公式求值:1.log2 25 ×log3 4 ×log5 9 2.(log4 3+log8 3)(log3 2+
计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15
已知log2[log4(log3x)]=log3[log5(log2y)]=0,求4更号x-y^1/5
计算(log4 3+ log8 3)(log3 2+ log9 2)-- log1/2 32^(1/3)+5^(log2
log4(log5 a)=log3(log5 b)=1,求a/b.
log2(3)*log3(5)*log5(8)(具体步骤)
