log3中2,A,LOG2 3是一个等差数列,求A
log2(3)=a,log3(7)=b.log12(56)=log3(7*8)=log3(7)+3log3(2)
log2^3 =a log3^7 =b 求用a,b表达log14^56
已知log2(3)=a[3为真数在上面],log3(7)[7为真数在上面],求log3√7^(2√21)的值.
log3^2=a,用a表示log2^12的值是
log2(3)+log3(5)+log3(2)=?
已知 log2(3)=A log3(7)=B 试求log14(56)
log2(3)=a,log3(7)=b,求log42(56)的值
已知log3^2=a则log2^9等于多少
若a=log2 3.b=log3 2,c=log1/3 2.d=log2 1/3
若a=log2 3,b=log3 2,c=log4 6比较大小
已知1/(log2^a)+1/(log3^a)=2.求a的取值
3/2,log3^5,log2^3的大小关系是
