log4(3)-log4(12)-log8(4) =log4(3/12)- log8( 8^(2/3) ) log8(

log4(3)-log4(12)-log8(4) =log4(3/12)- log8( 8^(2/3) ) log8( log4 8-log8 4=? (log4(3)+log8(3))*log3(2) (log4 3+log8 3)*(log3 2+log4 2) (log4(3)+log8(3))*(log3(2)+log8(2))-log1/2(^4√32)=? (log3^2 + log9^4)×(log4^3 + log8^3) 计算:(log4 3+log8 3)×log9 √2=? log4(3)+log8(3) 怎么相加? log4(3)+log8(3) 怎么算 log4 243 - log8 729=?log4 12 - log2 6=? 化简(log4(3)+log8(3))(log3(2)+log9(2)) (log4^3+log8^3)(log3^2+log9^2)
