3^1+log3^6 -2^4+log2^3+10^3lg3+9/1^log3^4

(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7) 1/(1+log3 2)+1/(1+log2 3)=lg3/(lg2+lg3)+lg2/(lg2+lg3)=1解释一下这 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 (log3^4+log5^2)(log2^9+log2^根号3) log3^36-log3^4+log2(log2^16)+8^2/3+(27/8)^-1/3+log8^27/log4^ log2(3)+log3(5)+log3(2)=? (log2(3)+log8(9))x(log3(4)+log9(8)+log3(2)) (log2 3+log8 9)(log3 4+log9 8+log3 2)的运算过程 计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15 [log2(3)+log4(9)][log3(4)+log9(2)]等于 log2 4=2log3 9=3
