log23=a,log35=b试用a,b表示log3045log23=a,log35=b试用a,b表示log3045log23=a,log35=b试用a,b表示log3045log23=a,log35
log2 3=a ,log3 5 =b 试用a,b表示log30 45
log2 3=a ,log3 5 =b 试用a,b表示log30 45
log2 3=a ,log3 5 =b 试用a,b表示log30 45
log2 3=a,log3 5=b,
∴ log3 2=1/a
∴ log30 45=log3(45)/log3(30)
∵ log3(45)=log3(3²*5)=log3(3²)+log3(5)=2+b
log3(30)=log3(2*3*5)=log3(2)+log3(3)+log3(5)=1/a+1+b=(1+a+ab)/a
∴ log30 45=log3(45)/log3(30)=(2+b)*a/(1+a+ab)
log2(3)+log3(5)+log3(2)=?
log2(log0.5(log2a))=0 log3(log1/3 (log3 b))=0 a,b的大小关系为?log2(log0.5(log2a))=0log3(log1/3 (log3 b))=0 a,b的大小关系为?
已知log2 ,3=a,log3,5=b,用a,b表示log15,20
log2 3=a ,log3 5 =b 试用a,b表示log30 45
log2 3=a,log3 5=b,试用a,b 表示log30 45
设log3 7=a,log2 3=b,则log2 7=?
log3(7)=a,log2(3)=b,则log2(7)=?
已知log3,7=a,log2,3=b,求log2,7的值.RT
(log2 6)×(log3 6)-(log2 3+log3 2)=
(log2 6)×(log3 6)-(log2 3+log3 2)=
log2(3)*log3(2)=?
(log3^2)(log2^3)=
已知log2 10=a,log3 10=b 则log3 4等于多少已知log2 10=a,log3 10=b 则log3 4等于多少
log2(a)=log3(b)=log5(c)
已知log2 3=a,log3 7=b,试用a,b表示log14 56
已知 log2 3=a,log3 7=b,试用a,b表示log14 56
已知log2 3=a,log3 7=b,试用a,b表示log12 56
已知log2^3=a,log3^7=b,试用a`b表示log14^56
