log4 (√(7+4*√3)-√(7-4*√3)=
log4 (√(7+4*√3)-√(7-4*√3)=
log4(1+√5-√3)+log4(1+√5+√3)=?
log4(√5-√3)+log4(√5+√3)=?
log4(3)-log4(12)-log8(4) =log4(3/12)- log8( 8^(2/3) ) log8(
(log4(3)+log8(3))*(log3(2)+log8(2))-log1/2(^4√32)=?
计算:(log4 3+log8 3)×log9 √2=?
log4(1+√2+√3)+log4(1+√2-√3)的值等于
计算:(log4 9+log8 3)(log3 2+log9 2)-log1/3 4√81
(log4^3+log8^3)*(log3^2+log9^2)-log2^4次√32
各位大神log4(3)log9(2)-log1/2(4√32)怎做啊?
log√3^9+log9^27+(1/4)log4^1/16
log4 2^3/2=log4 4^3/4 是怎么算出来的?(log4中的4为底数)
