Step-by-step explanation: swag drapery ideasNettetThe closure property of multiplication states that if a, b are the two numbers that belong to a set M then a × b = c also belongs to the set M. Let a, b ∈ N then a × b = ab ∈ N. Hence, Natural numbers are closed under multiplication. a, b ∈ Z then a × b = ab ∈ Z Hence, Integers are closed under multiplication. √3 ∈ Q’ then √3 × √3 = 3 ∉ Q’ skf2a fountainette

"In mathematics, a subset of a given set is closed under an operation of the larger set if performing that operation on members of the subset always produces a member of that subset. For example, the natural numbers are closed under addition, but not under subtraction: 1 − 2 is not a natural number, although both 1 and 2 are. Similarly, a subset is said to be closed under a collection of operations if it is closed under each … " - Integers are not closed under multiplication
