log48-log84=?log48-log84=?log48-log84=?log48=log2^22^3=log22^(3/2)=3/2所以:log84=2/3;所以:log48-log84=3/
log4 8-log8 4=?
log4 8-log8 4=?
log4 8-log8 4=?
log4 8
=log2^2 2^3
=log2 2^(3/2)
=3/2
所以:
log8 4=2/3;
所以:
log4 8-log8 4
=3/2-2/3
=5/6.
=log(2^2) (2^3)-log(2^3) (2^2)=3/2-2/3=9/6-4/6=5/6
log4 8-log8 4
=lg8/lg4-lg4/lg8
=lg(2^3)/lg(2^2)-lglg(2^2)/lg(2^3)
=3/2-2/3=5/6
3/2-2/3=5/6
log4 8-log8 4=?
log4(3)-log4(12)-log8(4) =log4(3/12)- log8( 8^(2/3) ) log8( 8^(2/3) )怎么得出来的?
log3(4)·log4(8)·log8(m)=log4(16)则m=
设log3(4)*log4(8)*log8(m)=log4(16)那么m等于~
若log3 4*log4 8*log8 m=log4 16求m
log3 4*log4 8*log8 m=log4 16,则m为[ ]其中3、4、8、4为底数.
log3^4乘log4^8乘log8^m=log4^2麻烦过程写清楚一点.谢谢、
若log3(4)×log4(8)×log8(m)=log4(16).则m等于?谢谢
log3 4×log4 8×log8 a=log根号3 9,则a=
log3 4*log4 8*log8 7*log7 m=1og3 18 求M 等于多少.
(log4(3)+log8(3))*(log3(2)+log8(2))-log1/2(^4√32)=?..
log4 2+log8 2=多少?
log3 4×log4 8×log8 m=log4 16,则m=( )(注:3,4,8是底数)请写出详细过程,
log3^4*log4^8*log8^m=log4^2 求mlog8^3=p log3^5=q用pq表示lg5
:若log3(4)*log4(8)*log8(m)=log4(16),则m等于( )A 1/2 B 9 C 18 D 27答案是B但为什么?
log4 243 - log8 729=?log4 12 - log2 6=?
[log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2)][log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2)
化简log3(4)*log4(5)*log5(8)*log8(9)的结果是?
