Lời giải:
Thể tích xe chở hàng: $4.2,5.2,4=24$ (m3)
Thể tích mỗi thùng hàng: $0,8.0,6.0,5=0,24$ (m3)
Nếu sắp xếp hợp lý thì xe chở được tối đa:
$24:0,24=100$ (thùng hàng)

\(25.5.4.27.2=\left(25.4\right).\left(5.2\right).27=100.10.27=27.1000=27000\)
25 tháng 10 2020
Ta có: 25.5.4.27.2 = 27 . (25.4) . (5.2)
= 27 . 100 . 10 = 27000
Cách thêm đuôi –er và –est (Spelling rules for the –er and –est ending) ... từ hoặc trạng từ có hai âm tiết tận cùng bằng phụ âm + y: đổi y dài + er/ est.
-er là dùng cho so sánh hơn của tính từ ngắn
-est là dùng cho so sánh nhất của tính từ ngắn
