2-log32/9+log3 8-5的(2倍的log5 3)
2-log32/9+log3 8-5的(2倍的log5 3)
2-log32/9+log3 8-5的(2倍的log5 3)
2-log3 2/9+log3 8-5的(2倍的log5 3)
=2-log3 2+2+3log3 2-3的平方
=4+2log3 2-9
=2log3 2-5
2log3 2-log32/9+log3 8-5^log5 3
2-log32/9+log3 8-5的(2倍的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
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?
2log3 2-log3 32/9+log3 8-3^2+log3 5 明天要交的
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
若log32 9=p,log3 5=q,如何用p.q表示lg5?
log3(log32) (log32)二次方比较大小
log3 2=m 试用m表示log32 18
知log3^2=m,用m表示log32^18
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)
2log3 2-log3 32/9+log3 8-3^2+log3 5
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
lg1/2-lg5/8+lg12.5-(log23)(log32)详细结果
2log3 2-log3 32/9+log3 8-5^2log5 3
2log3^2-log3^(32/9)+log3^8
