证明1/log5(16)+1/2log3(16)+1/3log2(16)＜1
证明1/log5(16)+1/2log3(16)+1/3log2(16)＜1
证明1/log5(16)+1/2log3(16)+1/3log2(16)＜1
1/log5(16)+1/2log3(16)+1/3log2(16)
=log16(5)+log16(3)^1/2+log16(2)^1/3
=log16(5*3^1/2*2^1/3)
因5*3^1/2*2^1/3
证明1/log5(16)+1/2log3(16)+1/3log2(16)＜1
log5·log5(3)·log5(1/3)log3(5)·log5(3)·log5(1/3)log3(2)·log5(3)·log8(5)不好意思
证明不等式1/log5(19)+2/log3(19)+3/log2(19)
证明不等式1/(log5(19))+(2/log3(19))+(3/log2(19))
8^(-1/3)+log3(1/27)+log6(5)*[log5(2)+log5(3)]+10^lg3=?
为什么1/log5(3)等于log3(5) ?
2007*log5(1)+log4(27)*log3(4)
log2(2)+log5(1)-log1/3(1/27)+[3^log3(5)]^2+3^-log3(2)=?
化简:log2 2+log5 1-3^(2log9 5)+(3log3 5)^2+3^log3 2
计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15
比较1/log5(19)+2/log3(19)+3/log2(19) 和 1/log2（派）+2/log5（派）大小
求 log5（35）+ 2log0.5（根号2）-log3（1/27）-log3（1/15）-log5（21）
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 5-log3 15
1、计算log5^35+2log1/2^根号2-log5^1/50-log5^14 2、已知log3^7=a,log2^3=b,求log21^28
log3^2*log5^7/log9^1/7*log125^82.log2^3=1-a/a,则log3^12=
计算log2为底25*log3为底1/16log5为底1/9
计算:log3 8×log4 27+5^(1-log5 2)+(27/8)^-(2/3)+sin3π/2
1/log5^7+1/log3^7+1/log2^7 ,求值
