log3 8/log3 2等于多少?急用!

已知log3^2=a则log2^9等于多少 log3(log2x)=1,则 x^1/2等于多少 若2X=8,则log3根号X等于多少 (-27/8)^3+(2-根号三)^0-1/9*log2^9*log3^4等于多少 log2 9乘以log3 4等于多少 log2(3)=a,log3(7)=b.log12(56)=log3(7*8)=log3(7)+3log3(2) log3*4为什么等于log4/log3 2log3底2-log3底32/9+log3底8 (log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7) 已知log2 10=a,log3 10=b 则log3 4等于多少 解不等式（2+log3 x)log3 x>log3 (9x) 【[log3(lgx)]=1】【logx(8)=3/2】【5^lgx=25,】,各求x等于多少?②
