(log2)和(log3)变成(log5)(log2)和(log3)变成(log5)(log2)和(log3)变成(log5)要求log5跟log3是没有关系的log5的求法是1-log2也就是log
(log2)和(log3)变成(log5)
(log2)和(log3)变成(log5)
(log2)和(log3)变成(log5)
要求log5 跟log3是没有关系的
log5的求法是 1-log2 也就是log10-log2=log10/2=log5
log2大约为0.3010 所以log5=1-0.3010=0.6990
(log2)和(log3)变成(log5)
log2[log3[log5 125]]=?log2[log3[log5 125]]=?
log5[log2(log9/log3)]=?
比较1/log5(19)+2/log3(19)+3/log2(19) 和 1/log2（派）+2/log5（派）大小
计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15
(log3^4+log5^2)(log2^9+log2^根号3)
高中数学题log2^25 * log3^4 * log5^9
log2^25*log3^2倍根号2*log5^9=
log2^5*log3^2倍根号2*log5^9=
log3 25×log2 27×log5 2^-3=_____
log2(a)=log3(b)=log5(c)
log5［log2（log3 9）］=
log2 5*log5 81*log3 4+ln根号e
1/log5^7+1/log3^7+1/log2^7 ,求值
若log2(x)=log3(y)=log5(z)
log5[log3(log2^x)]=1,x=
log2(3)*log3(5)*log5(8)（具体步骤）
log2(2)+log5(1)-log1/3(1/27)+[3^log3(5)]^2+3^-log3(2)=?
