Question

Determine os elementos do conjunto A={x E Z* | -8 < x < menor igual 21

Answer 1

Olá!

A = { x ∈ Z* | -8 < x ≤ 21 }
A = { -7, -6, -5, -4, -3, -2, -1, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21}

Espero ter ajudado!

Answer 2

A = {x ∈ Z* / -8 ∠ x ≤ 21 }
A = {-7,-6,-5,-4,-3,-2,-,1,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21}
