Question

Dados os conjuntos A-{5,6} e B={-1,3,4,5}, Determine

A) AXB
B) A²
C) B²

Answer 1

a) A x B = {5 x -1, 5 x 3, 5 x 4, 5 x 5, 6 x -1, 6 x 3, 6 x 4, 6 x 5} = {-5,15,20,25,-6,18,24,30}

b) A² = {5²,6²} = {25,36}

c) B² = {(-1)², 3², 4², 5²} = {1,9,16,25}

Answer 2

 A-{5,6} e B={-1,3,4,5}, Determine

A) AXB = {(5,-1),(5,3)(5,4)(5,5), (6,-1),(6,3)(6,4)(6,5) }
=======================================================
B) A² =  A x A

 {(5,5),(5,6), (6,5),(6,6) }
=========================================================
C) B² =  B x B 
{(-1,-1),(-1,3)(-1,4)(-1,5), (3,-1),(3,3)(3,4)(3,5){(4,-1),(4,3)(4,4)(4,5), (5,-1),(5,3)(5,4)(5,5) }
