log2 1-lg3×log3 2-lg5
lg2+lg5-log2(3)乘log3(2)
1/(1+log3 2)+1/(1+log2 3)=lg3/(lg2+lg3)+lg2/(lg2+lg3)=1解释一下这
计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15
已知lg2=a,lg3=b求:(1)lg6= (2)log3;4= (3)log2;12= (4)lg3/2=
已知lg2=a,lg3=b,求下列各式的值 (1)lg6 (2)log3|4 (3)log2|12 (4)lg3/2
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
计算 lg3*log3^4+(lg5)^2-(lg2)^2+(根3-根2)^-1-根号下5-2倍根号6e^2分之1ln2
2^log2 (3) × log2 (1/8) + 2lg3
(lg3(lg2+lg5)/lg2lg5) *[ lg5(lg3+lg9)/lg3lg9]*lg2=(lg3+2lg3)
lg2/lg3+lg5/lg3
log2(3)+log3(5)+log3(2)=?
10^lg3-根号10log4 1+2^log2 6
