log2^3*log3^7*log7^8
log2^3*log3^7*log7^8
log2(3)*log3(4)*log4(5)*log5(6)*log6(7)*log7(8)=?
log2(3)+log3(4)+log4(5)+log5(6)+log6(7)+log7(8)
log2为底3*log3为底4*log4为底5log5底6*log6底7*log7底8=
(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7)
我是这样做的log2(3)*log3(5)*log5(49)*log7(64)=log2(3)*log3(5)*2log
求值 3^2-log3(2)= log7(log5(log2(32)))=?
log2 3×log3 7=log2 7
log3 (4√27)/3 +lg25 +lg4 +7^(log7 2)
简单的对数题几枚已知log2 3=a,log3 7=b试用a b表示log14 56比较大小 log6 7 log7 6
log2 (1/49))×log3 (1/16)×log7 (1/27)
log2(3)=a,log3(7)=b.log12(56)=log3(7*8)=log3(7)+3log3(2)
