3^-log3^2怎么化简
3^-log3^2
=3^log3^(2^-1)
=2^-1
=1/2

log3 72-3log3 2 =log3 72-log3 2 3; =log3 72-log3 8 =log3 (72/8) =log3 9 =log3 3 2; =2log3 3 =2

log3 72-3log3 2 怎么化简 3^-log3^2怎么化简 2log3^2-log3^(32/9)+log3^8 怎么化简? log3/2乘以5log2/3怎么化简? 3^(log3 ^2)怎么计算 log3 8除以log3 2怎么计算 log3^2怎么计算 log3(log3100) 如何化简log3的(log3的100) log2(3)+log3(5)+log3(2)=? -5log9(4)+log3(32/9)-(1/64)^(-2/3),怎么化简,要步骤谢谢.RT 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 log3¹²怎么化成2log3²+1 log3(2)和log4(3)用换底公式怎么比较呢 log 243÷log9 =log3^5÷log3^2 =log3^5-log3^2 然后怎么写 已知log（32）9=p,log（27）25=q,适用p,q表示lg5p=log32(9)=2/5×log2(3)=2/5×1/log3(2)∴log3(2)=2/5pq=log27(25)=2/3×log3(5)∴log3(5)=3q/2lg5=log3(5)/log3(10)=log3(5)/[log3(2)+log3(5)]=15pq/(4+15pq)结果怎么出来的? log3(x^2-3)=1+log3(x-5/3) 计算log3[(9^2 * 27^(1/3))/3^(log3 234)]
