log3 6+log3 5-log3 10 计算题

log3 6+log3 5-log3 10 计算题 log3(x^2-3)=1+log3(x-5/3) log3 5-log3 15+1/2log9 27 的值 一道对数计算,log3(27/5)+log3(2/3)-log3(6/5) 计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15 为什么lg5=log3(5)/log3(10) log2(3)+log3(5)+log3(2)=? log3(5)/log3(10)怎么算的? log3 1等于几 log3(lgx)=1 2log3 2-log3 32/9+log3 8-3^2+log3 5 2log3 2-log3 32/9+log3 8-3^2+log3 5 明天要交的 log3 18-log3 2=log3 16? 计算(log3 2)(log2 6-1) 若数列{an}的前n项和公式为Sn=log3(n+1),则a5等于?A.log5^6B.log3^五分之六C.log3^6D.log3^5 为什么1/log5(3)等于log3(5) ? 3^(1+log3 6) -2^(4+log2 3)+10^3lg3+(9/1)^log3^4题有个错误，+(9/1)^log3^4改为+(9/1)^log3^4-1 log3^9/4+log3^4
