Giải thích các bước giải:
`a) 10 ≤ x < 15`
`⇒ x = 10 ; 11 ; 12 ; 13 ; 14`
`⇒ m = {10 ; 11 ; 12 ; 13 ; 14}`
`b) x ≤ 3 ; x ∈ N**`
`⇒ x = 1 ; 2 ; 3`
`⇒ k = {1 ; 2 ; 3}`
`c) x ≤ 3 ; x ∈ N`
`⇒ x = 0 ; 1 ; 2 ; 3`
`⇒ l = {0 ; 1 ; 2 ; 3}`
`a ) M = {x ∈ N | 10 ≤ x < 15}`
`=> M = {10 ; 11 ; 12 ; 13 ; 14}`
`b ) K = {x ∈ N`* `| x ≤ 3}`
`=> K = {1 ; 2 ; 3}`
`c ) L = {x ∈ N | x ≤ 3}`
`=> L = {0 ; 1 ; 2 ; 3}`
