算2log32-log32/9+log38-5^2log53.算2log32-log32/9+log38-5^2log53.算2log32-log32/9+log38-5^2log53.log32/9
算 2log3 2-log32/9+log3 8-5^2log5 3 .
算 2log3 2-log32/9+log3 8-5^2log5 3 .
算 2log3 2-log32/9+log3 8-5^2log5 3 .
log3 2/9=log3 2-log3 9=log3 2-2
log3 8=3log3 2
5^2log5 3=5^log5 9=9
所以2log3 2-log32/9+log3 8-5^2log5 3=4log3 2 - 7
2log3 2-log32/9+log3 8-5^log5 3
算 2log3 2-log32/9+log3 8-5^2log5 3 .
计算 2log3 2-log32/9+log3 8-5^log5 3
计算 2log3 2-log32/9+log3 8-5^log5 3
2-log32/9+log3 8-5的(2倍的log5 3)
log3 2=m 试用m表示log32 18
知log3^2=m,用m表示log32^18
你可以将原式变为 log23+log32 =log23/log22+log22/log33 =log3/1+1/log3 =log3+1/log3 相信你知道log(2)xalogaM=M怎么算的
已知log3 2=m,使用m表示log32 18过程
已知log3(2)=m,试用m表示log32(18)
log3(log32) (log32)二次方比较大小
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?
设函数f(x)=log3((x-2)/x-a)在区间(1,2)内有零点,则实数a的取值范围是()A.(-1,-log32) B.(0,log32) C.(log32,1) D.(1,log34)
求值(log43+log83)(log32+log92) 注:log后面那为数是底数=5/6*log3/log2*3/2*log2/log3=5/4 怎么来的
log34=2log32为什么
2log3^2-log3^(32/9)+log3^8
设函数f(x)=log3((x-2)/x-a)在区间(1,2)内有零点,则实数a的取值范围是() A.(-1,-log32) B.(0,log32设函数f(x)=log3((x-2)/x-a)在区间(1,2)内有零点,则实数a的取值范围是()A.(-1,-log32) B.(0,log32) C.(
(log3^14-log3^2)log7^9求值
