WebSome of the important properties of Cartesian products of sets are given below. (i) Two ordered pairs are equal, if and only if the corresponding first elements are equal and the second elements are also equal. (ii) If there are m elements in A and n elements in B, then there will be mn elements in A × B. Web16 jun. 2024 · Cartesian Product of Sets: The Cartesian product of two non-empty sets A and B is denoted by A×B and defined as the “collection of all the ordered pairs (a, b) such that a ∈ A and b ∈ B. a is called the first element and b is called the second element of the ordered pair (a, b). A×B = { (a, b) : a ∈ A, b ∈ B}

Web6 sep. 2024 · Finding A: N can be represented as a series of bits of 0 and 1. To find A we will first have to find the most significant bit of N which is set. Since A & N = 0, The places where N has set bit, for that places we will make bits of A as unset and for the places where N has unset bit, we will make that bit set for A as we want to maximize A. WebFor non-empty sets A and B, if A ⊂ B then (A x B) ∩ (B x A) is equal to (1) A ∩ B (2) A x A (3) B x B (4) none of these. Solution 12. The number of relations on a set containing 3 elements is (1) 9 (2) 81 (3) 512 (4) 1024 Solution Let S = {a,b,c} n(S) = 3 n(S x S) = 9 Number of relations in n {P (SxS)} = 29 = 512 13.
Web4 Maybe you could show this relation in an other way: [A, Bn] = [A, Bn − 1B] = Bn − 1[A, B] + [A, Bn − 1]B =... Then you take [A, Bn − 1]B and repeat the process: [A, Bn − 1]B = [A, Bn − 2B]B = Bn − 2[A, B]B + [A, Bn − 2]BB So B commute with [A, B] [A, Bn − 1]B = Bn − 1[A, B] + [A, Bn − 2]B2 Repeat for n steps Web5 nov. 2024 · Let A and B are two sets.
