2007*log5(1)+log4(27)*log3(4)
2007*log5(1)+log4(27)*log3(4)
计算:log3 8×log4 27+5^(1-log5 2)+(27/8)^-(2/3)+sin3π/2
log 2 3 * log3 4 * log4 5 *log5 2 化简
log3(4)*log4(5)*log5(6)*...*log80(81)
log4(log5 a)=log3(log5 b)=1,求a/b.
log5[log4(log3 81)]=0
1.log2 3*log3 4*log4 5*log5 2 2.(log4 3+log8 3)8(log3 2+log9
比较下列各数的大小:2^0.7,log5(4),log1/3(5),log3(1/4),log4(1/3),
已知log2[log4(log3x)]=log3[log5(log2y)]=0,求4更号x-y^1/5
1/log2 (11) +1 /log3(11)+1/log4(11)+1/log5(11)
化简:1/log3(x)+1/log4(x)+1/log5(x)=
运用对数换底公式化简log2(3)*log3(4)*log4(5)*log5(2),
