log3+log16-log4-log12

log3+log16-log4-log12 log6[log4(log3^81)] log3*4为什么等于log4/log3 设p,q满足log9(p)=log12(q)=log16(p+q),求q/p的值 33.不用计算器,证明：[log6]^2=/=log3*log12 [log4(3)/log4(8)][log3(2)log9(2)] (log4 3+log8 3)*(log3 2+log4 2) 2007*log5(1)+log4(27)*log3(4) 比较log3 (2),log4 (3)大小 求log3^2*log4^9的值 (log4(3)+log8(3))*log3(2) log5[log4(log3 81)]=0
