化简log3(5)+log5(3)-log3(15)*log5(15)

化简log3(5)+log5(3)-log3(15)*log5(15) 2log3^2-log3^(32/9)+log3^8-5log5^3=5log5^3改成5^log5^3 为什么1/log5(3)等于log3(5) ? log5·log5(3)·log5(1/3)log3(5)·log5(3)·log5(1/3)log3(2)·log5(3)·log8(5)不好意思 化简:log2 2+log5 1-3^(2log9 5)+(3log3 5)^2+3^log3 2 2log3 2-log32/9+log3 8-5^log5 3 计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15 log6(x)/log6(3)为什么等于log3(x)log3(x)/log3(5)为什么等于log5(x) 2log3 2-log3 32/9+log3 8-5^2log5 3 log3^2/3与log5^6/5比较大小 log3^2/3与log5^6/5比较大小 log3^2/3与log5^6/5比较大小 log2(3)*log3(5)*log5(8)（具体步骤） 数学对数知识,为什么5^log3=3^log5为什么5^log3=3^log5,是怎么来的, 8^(-1/3)+log3(1/27)+log6(5)*[log5(2)+log5(3)]+10^lg3=? log2(2)+log5(1)-log1/3(1/27)+[3^log3(5)]^2+3^-log3(2)=? 计算 2log3 2-log32/9+log3 8-5^log5 3 算 2log3 2-log32/9+log3 8-5^2log5 3 .
